Barth Electronics, Inc.
Company Background - Pulse Power Division
Barth Electronics, Inc. has been designing and manufacturing "state of theart" sub-nanosecond high energy, pulse power coaxial components since1964. Our first high voltage pulse instrumentation hardware was designed forunderground nuclear testing, and taught us much about reliable wideband HV
attenuators. These "special" products have become "STANDARDS" and areused every day for reliable pulse measurements in physics and pulse powerlaboratories around the world. Our instrumentation advances developed ashigh voltage pulse technology evolved, (and has been consistently faster thanpulses that could be generated). We stay at the leading edge of thistechnology by constantly creating innovations in component design that you
require now, or will need tomorrow.
The resistor used in our attenuators, terminators, and voltage probes has
many capabilities designed specifically for high voltage pulse use. It has avery low voltage coefficient of resistance, which is why our components
provide the same accurate measurements at millivolt or kilovolt signal levels.
Their low temperature coefficient of resistance also provides minimal
attenuation change with temperature and our resistors are held to 50 ohms
0.5 ohms for accurate and repeatable attenuation measurements.
Our microwave and HV design capabilities have enabled us to put our
resistors into coaxial housings that provide the best pulse response possible
for their rated energy. The combination of these capabilities provides you withthe fastest pulse rated components available.
Our attenuator design capability continues to evolve and has resulted in
improved pulse response, voltage rating and in greatly increased average
power rating. Our components remain the best high voltage coaxial devices
available anywhere.
We strive to minimize your problems in interconnection of measuring
instrumentation by providing many different coaxial connectors with close
tolerances on our products. We offer type "SMA", “TNC”, “BNC”, "N", “SHV”
and "HN" connector selections on many of our standard products.

We are working on the design of new and higher voltage connectors for use
with your constantly increasing pulse voltages.
Our high voltage probes are usually designed to meet specific requirementsof resistance, voltage, pulse width, risetime, and physical dimensions foreach application. They are presently being used in air, vacuum, and water
systems, with risetimes as fast as 100 picoseconds, and voltages as high as
500kV.
Our line of pulse transformer components has less loss and narrower
bandwidth than resistive units for dividing, combining, or signal sampling. We
make several extremely wide bandwidth reactive units that have high energy
capability as well. We have developed a 50 picosecond risetime pressurized
reed switch pulse generator that has an output voltage that is adjustable from100 to 2500 volts.
Our waveform modification capabilities include impulse, linear ramp, stairstep
generators and risetime spoilers and positive exponential generators. Units
have been produced that can operate up to 10kV and are a fast as subnanosecond or as slow as 100 ns risetimes.

We are continuously investigating new technologies that can be applied to EM measurements
and are designing new products as needs arise. If we have not already designed what you need,
we have other sources that may be helpful with your high voltage measurements.
Call us to discuss your pulse measurement needs.

TECHNICAL SPECIFICATIONSTESTING FOR GUARANTEED PERFORMANCE
Components are 100% tested with 1000 pulses at their rated voltage and pulse width. The resistance of all
ports is measured before and after HV testing. Each unit passes this test only if its resistance, after HV pulsing,increases less than 0.04%. Any higher increase indicates a breakdown, and that unit is rebuilt and retested. In
addition to the DC resistance measurements, each unit is also tested for pulse response and reflection
coefficient to be certain they meet our specifications. The pulse amplitude and width capability of a unit listed
as 5kV/400ns means that it is guaranteed to withstand 5kV rectangular pulses that are 400ns long. We
recommend that DC resistance tests be performed regularly on all of your resistive attenuators, of any
make, as an easy detection of resistor failure. All of our products are guaranteed to perform to their
specifications indefinitely when used within its specifications.

MAXIMUM INPUT LIMITATION
The voltage specification of our products is sometimes limited by the breakdown characteristics of theconnectors. The voltage limits we use for our specifications are 4kV for the "N" connector, 6kV for the GR 874
connector and 13kV for the "HN" connector. These limitations are for DC, and provide a safety factor for ourpulse length ratings. The "N" connector, for instance, can pass 10kV at short (10ns) pulse widths.
The breakdown limitations of our film resistors are related to pulse energy. A unit that has been tested towithstand 5kV, 400ns FWHM rectangular pulses should be able to withstand 10kV, 75ns FWHM rectangularpulses. While this general "rule of thumb" has been found to be useful in practice, we cannot guarantee higher
voltages or pulse widths unless we test the particular unit to your pulse specification.
Some units have been designed and rated to withstand exponentially decaying pulses and are listed witha 1/ε notation. An exponentially decaying pulse with a 1/ε time constant has half the energy of a rectangularpulse, with the same FWHM time. Therefore, our resistive units can withstand exponential pulses that have atime constant twice as long as a rectangular pulse.
Please call if your pulse measurement requirements cannot be met by the standard product specifications.

VOLTAGE COEFFICIENT OF RESISTANCE
The voltage coefficient error of our resistive components is less than 1 % at their rated voltage. It is
usually significantly lower than this but we cannot specify it any better because of present measurement
limitations. See our Application Note for further information regarding the importance of Voltage
Coefficient in pulse voltage measurement.

PULSE RISETIME
The 10%-90% risetime through our attenuators is listed as τ (tau). It is calculated by taking the square rootof the difference between the observed risetime squared and the input risetime squared. This would be therisetime out of our attenuator with a perfect (zero risetime) input. Our risetime and reflection coefficientmeasurements are made with a 54120A HP digital sampling system that can be normalized to as fast as
10ps.

VOLTAGE COEFFICIENT OF RESISTANCE
Application Note #1
positive voltage coefficient. This voltage dependent change ofresistance happens instantaneously and can be observed to occur inless than 1 nanosecond. If the period of voltage application is too
long, the temperature may rise and cause large resistance changes
that can mask voltage coefficient effects.

The purpose of this application note is to describe some importantconsiderations in high voltage pulse measurements with resistors
as dividing elements. The term "Voltage Coefficient ofResistance" has been around for a long timeP1P; but is seldom
used or well understood. As high voltage pulse measurements
improve, and higher accuracy becomes available, voltage
coefficient errors that could once be ignored now must be
considered.

Short pulses applied to many resistors will show voltage
coefficient effects during the time the voltage is applied. Althougha resistor may not burn out during extensive pulsing, or have apermanent resistance change, it can have significant voltage
coefficient changes during the time of the pulse.

It is well known that the resistance increases with temperaturerise of nearly all resistors, including the commonly encounteredcarbon composition resistor. The temperature coefficient ofresistance (of a resistor) may be expressed as the ratio of theresistance change to the temperature rise. Such a temperature
coefficient classification is useful if the resistance changes
uniformly with temperature rise and fall.

The voltage coefficient varies with different resistive
materials, and seems to be greatest for materials that are composedof a granular conglomeration of resistive material held together
with an insulating binder. Carbon composition and cermet film
resistors use these types of resistive materials.

Resistors undergo temperature variations not only due tochanges in ambient temperature, but also due to dissipation ofelectrical energy when current is passed through them. It is
desirable in measurements using resistors, that their temperature
coefficient be small to minimize errors. One can see, for example,
that when a measurement apparatus involving resistors iscalibrated at low signal levels, the calibration may be invalid at
higher signal levels if the resistance values change.

Nonlinear resistivity can easily be displayed by placing asmall amount of finely powdered conducting or semiconducting
material between two skewed small diameter wires. Graphite,
shaved from a pencil or from a carbon composition resistor
displays this effect nicely. The effect can be observed using as
little as 1 volt between the two wires. The nonlinear voltage versus
current ratio can easily be seen on a simple transistor/ diode curve
tracer as a nonlinear slope. This nonlinear resistance occurs forboth positive and negative voltages and is symmetrical if there is
no rectifying contact. Of course, resistors of a few thousandths ofan inch in length are not used in high voltage applications; but if
you put 1,000 of these small resistors mentioned above, that are
three thousandths of an inch long, in series, you would have aresistor three inches long. This resistor, assembled from many low
voltage nonlinear junctions, would have a nonlinear resistancewhen used at 1,000 volts.

It has also been known for a long time1 that the resistance ofa resistor can change due to a change in the voltage applied to it,even though the temperature may be held constant. The voltage
coefficient of resistance may be expressed as the ratio of theresistance change in ohms to the corresponding increase in applied
voltage in volts when the temperature is held constant. Suchvoltage coefficient of resistance definition is useful to characterize
the resistance change with an increase in applied voltage. Of
course, for any useful resistor material, the resistance returns to its
original value when the applied voltage is removed.

The voltage coefficient of resistance of the resistor depends
not only upon the length of the resistor, but also upon the
conductive interfaces between the resistive particles that make up
the resistor. These interfaces result in emission current (tunneling)
across microscopic gaps between conductive particles such asgraphite. It is complicated by many factors such as size ofparticles, their size distribution, and electron emission coefficients.
If resistance can be obtained without resorting to high resistancecontacts between granular low resistivity materials, then low
voltage coefficients can be achieved.

When a steady voltage is applied to a resistor, it normally
undergoes resistance changes due to both applied voltage andtemperature increase. The temperature increase is caused by thedissipation of electrical energy in the resistor due to current flow.
At low voltages the temperature coefficient is usually larger thanthe voltage coefficient. This change in resistance is almost entirely
due to a temperature change in the resistor.
When a short pulse is applied to a resistor, and very little
average power is dissipated in the resistor, its temperature will not
rise appreciably. Most of the resistance change of a lowtemperature coefficient resistor will be due mainly to theapplication of voltage, and limited to the time when the voltage isapplied. When high voltage pulses are applied to low value
resistors, the change in resistance can be appreciable, and can bevery important in measurement applications.

Bulk metal resistors have almost unmeasurable voltage
coefficients. However, due to the low resistivity of metals, wire
wound resistors must be used to achieve reasonable resistancevalues. The combined inductance and capacitance effects of wire
wound resistors prevent their use either at high frequencies or with
fast pulses.
Thin metal film can also be used to achieve reasonable
resistance values, but these resistors have a high voltage
coefficient. This may result from the extremely thin metal film
deposited on a very rough ceramic substrate, that allows tunnelingor current flow across the ceramic valleys.

Measurement of short high voltage pulses are made ininvestigations of the effects of lightning strikes, EMP testing onelectrical equipment, instrumenting underground nuclear tests, andthe pulse power industry.
Most resistors have a negative voltage coefficient, whichmeans that at higher voltages, the resistance decreases during thepulse. If the resistance increases with voltage, the resistor has a

Carbon composition resistors are made with powdered or granulargraphite material, which has a relatively low bulk resistivity.

VOLTAGE COEFFICIENT OF RESISTANCE
Application Note #1
Many different resistivity compositions are made to cover the 10
ohm to 10 megohm resistor range. The graphite/insulator
compositions are held in place with a phenolic binder that also
anchors the wire terminals into the carbon resistance element. This is
the original construction method for carbon composition resistors andcreates a robust and inexpensive resistor.

application of a 2kv, 100ns wide pulse. In pulse tests at 3kV with thesame value resistors, a 1 watt resistor decreased approximately 15%,
and a 1/2 watt resistor decreased approximately 6%.*
An additional factor that probably contributes to a decrease inresistance upon the application of high voltage is the effect of theswaged tinned metal contacts of these resistors. They protrude into
the bulk resistive material in such a way as to cause non-uniform
current distribution at both ends of the resistor.

Ordinary carbon composition resistors normally are made in 1/4,
1/2, 1, and 2 watt sizes. Our measurements found the 2 watt size tohave a much higher voltage coefficient than the 1 watt size, and the
1/2 watt size to have the lowest voltage coefficient over all. It wasalso found that the voltage coefficient of any particular wattage rating
is not much different between manufacturers. This would lead us tobelieve that something in the basic manufacturing process of this typeof resistor may be responsible for its very high voltage coefficient.

In high voltage pulse testing, inaccurate results are obtained
when high voltage coefficient resistors are used for voltage division
or attenuation measurements. The measurement of voltage coefficientof resistance can be accomplished at audio and radio frequencies bymeasuring the production of harmonic signals due to resistor
nonlinear behaviorP3P. We have developed additional measurement
methods using voltage pulses, and will continue resistor andattenuator testing.

In order to increase the surface area of a carbon composition
resistor and allow it to dissipate more energy, the size of the resistor
is increased. Increasing the size of the resistor will usually decrease
its resistance unless one increases the resistivity of the bulk material
to compensate for the increase in cross sectional area. For example atypical 1/2 watt resistor,P2 Phas a length of 0.375 inch and a diameterof 0.140 inch. The typical 2 watt resistor has a length of 0.688 inch
and a diameter of 0.318 inch. The length has been increased by afactor of 1.8, and the diameter by a factor of 2.27, so that the crosssectional area has increased by a factor of 5.2. The resistance of acylindrical resistor would be R = r I/A, where r is the resistivity of thebulk material, I is the length, and A is the cross sectional area. The
resistance would be increased by a factor of 1.8 due to the longer
length, and decreased by a factor of 5.2 due to the larger crosssectional area. This example assumes parallel end terminals, althoughcommercial carbon composition resistors have very non-uniform end
terminals.

We hope this information helps provide a better understandingof voltage coefficient and the causes of resistance changes at highvoltage. Reduced accuracy is the result of using common resistors inhigh voltage pulse measurements. The effect of voltage coefficientand the importance of using resistors with a low voltage coefficient inhigh voltage measurements is gradually becoming more widely
appreciated.
Because future designs are based on voltage measurements
made today, it becomes obvious that the use of low voltage
coefficient resistive instrumentation is essential for tomorrow's
designs.
_____________________________________________________*This agrees within the limit of 0.02 percent per volt
quoted by G.W.A. DummerP4P. The results quoted for 1 megohm
resistors of 1/4 to 2 watt ratings by F. LangfordSmithsP5P cannot becompared to those obtained at Barth Electronics, Inc., because there
is no information on the dimensions of the resistors, and because
Barth Electronics test resistors had lower resistance values.

In order to maintain the same resistance, in going from 1/2 wattsize to the 2 watt size, the resistivity of the bulk material must be
increased by a factor of 2.9. The resistivity depends upon the ratio ofgraphite particles (and their size distribution) to the insulating bindermaterial. A higher resistivity is achieved by decreasing this ratio,
using more binder or less graphite in the mixture. Therefore, theresistance material of a 2 watt resistor has a smaller percentage ofgraphite, than a 1/2 watt resistor with the same value. Fewer contacts
between granular resistor particles results in more tunneling, causing
a higher voltage coefficient.

The mechanism that causes resistors to change value with theapplication of voltage is difficult to define with certainty. However,
the evidence for such a change is real, and substantial changes inresistance can be observed. In one of our tests, the resistance of a 2
watt carbon composition resistor was observed to decrease from 390
ohms to 200 ohms during pulse testing. The high voltage resistance
was approximately 51% of the resistance at low voltage during

Information on HN and barth HNB Connectors:
The Barth HNB connector was specifically designed to provide both high voltage pulse capability and fastrise time performance in an HN compatible connector. These two characteristics are not available, both
together in any other commercially available HN connector.
While the HN connector interface is not quite as good as the precision N connector, it is still a very
respectable connector and has the advantage of withstanding much higher voltages. The HN connector
to connector interface will handle 15kV DC at sea level and somewhat higher pulse voltages.
However all HN connector to cable interfaces are not created equal, some are capable of handling highvoltages and others are not! The high voltage limitations of a cable connector, or any connector for thatmatter, are often limited by the transitions on the end of the connector opposite the connector toconnector interface. This is especially true of cable connectors, where the center conductor to outerconductor air gap spacing at the cable to connector transition is often not designed for high voltage, thatis, it is shorter than the connector interface air gap spacing. A real danger in this is that breakdown can be
occurring inside a connector and it will most likely not be apparent at the connector interface.
The Amphenol UG-59B/U male HN cable connectors as well as the Barth 401-HNB male HN cableconnectors have a cable to connector interface (center conductor to outer conductor) air path which is 50%
longer than the HN to HN interface air path, and thus gives these connectors good high voltage capability.
The easiest, and typical design,(as used in the Amphenol UG-59B), to make an HN cable connector handle
high voltage is to cut the cable insulation off square and then have the connector insulator overlap the cableinsulation by a length which is longer (commonly 50%) than the connector to connector interface air gap
path. While this does a good job of providing high voltage capability, it causes a severe discontinuity which
limits the bandwidth of this connection.
The Barth 401-HNB male HN cable connector is designed to handle high voltage and provide the best
possible bandwidth. The way we provide both high voltage capability and wide bandwidth is to cut down
the diameter of the insulation, in the cable to connector interface area, with a special hand tool. The
connector insulator will then overlap this area to provide the high voltage capability, and it is made thecorrect diameter to also provide the correct impedance, which eliminates the discontinuity and therefore
the bandwidth limitations inherent of the typical dielectric overlap used in the typical high voltage HNconnectors.
Other HN Connectors such as the Kings KH-59-19 male HN cable have an improved RF specification.
This improved bandwidth typically is the result of shortening of the dielectric overlap area, and thus
creates a reduction in the length of mismatched impedance. This improvement for bandwidth comes atthe expense of lower voltage handling capability in the cable to connector interface. In the case of theKings KH-59-19 male HN cable connector, the cable to connector interface (center conductor to outerconductor) air path is 50% shorter than the HN to HN interface air path, and thus makes this connector
unsuitable for high voltage applications. The shorter air gap in the coax to connector interface will almost
always break down before break down occurs in the connector interface (where it would be more easily
detected).
The Barth HNB interface is completely compatible with the standard HNB interface and when 2 HNB
connectors are mated you have the best available match for HN type connectors. If your fast pulse risetimes are slower than 0.5ns, you probably wouldn’t benefit from the advantages of the Barth HNB
connectors, but if your pulse rise times are on the order of 200-300ps then you would see some benefit,
and if your rise times are faster than 100ps the HNB connectors are a must.
If your application does not need the wide bandwidth of the HNB connectors, just insure that the HNconnectors you are using have a cable to connector interface that will handle your highest pulse voltage
pulses.
We hope this information will help you to achieve good test results using HN connectors.

Information on Barth BE 40kV Connectors:
The Barth BE connector is a unisex connector with a mating bullet that was specifically designed toaddresses the Pulse Power need for a connector that will take higher voltage than an HN connector,
and can still pass fast sub-ns pulse rise times. While the HN connector to connector interface willhandle 15kV DC at sea level and somewhat higher pulse voltages. The BE connector to connector
interface will handle 40kVDC, at sea level and somewhat higher pulse voltages. The BE connector
provides both fast rise time performance, and high voltage pulse capability, for applications up to 40kV.
These two characteristics are not both together available in any other commercially available connector
at this voltage rating.
Most high voltage connectors are not designed to be wide bandwidth; likewise most RF connectors are
not designed to handle high voltage. There are a few RF connectors on the market that will handle 20 to
25kV pulses, and some are matched better than others for rise time performance. Most are limited to aparticular cable type, and others are only found on pulse generators and are supplied with the mating
connector on a piece of coax.
The high voltage limitations of a coaxial cable connector are often determined by the cable to connectortransition, the end of the connector opposite the connector to connector interface. Coaxial cableconnectors are typically designed for RF performance, and not with high voltage in mind. Most often thecenter conductor to outer conductor air gap spacing at the cable to connector transition is not designed
for high voltage, that is, it is shorter than the connector interface air gap spacing. A real danger in this isthat breakdown can be occurring inside a connector and it will most likely not be apparent at theconnector interface.
The coaxial connector, cable to connector interface air path (center conductor to outer conductor), for awell-designed high voltage connector, is made to be longer than the connector to connector interface air
path, and thus gives the connectors reliable high voltage capability. The easiest, and typical design tomake a cable connector handle high voltage is to cut the cable insulation off square and then have theconnector insulator overlap the cable insulation by a length which is longer (commonly 50%) than theconnector to connector interface air gap path. While this does a good job of providing high voltage
capability, it causes a severe discontinuity which limits the bandwidth of these connectors.
The Barth BE connector is designed to provide the best possible bandwidth and to also reliably handle
high voltage. The way we provide both is to cut down the diameter of the cable insulation in the cable
to connector interface area with a special hand tool. The connector insulator will then overlap this area
to provide the high voltage capability. This allow us to also maintain the correct dielectric diameter toprovide the correct impedance, which eliminates the discontinuity and therefore the bandwidth
limitations inherent of the typical dielectric overlap design used in most high voltage connectors.
The Barth BE interface is now standard on many of our higher voltage products, and we offer a cableversion for RG-214 cable. Other versions will soon be available for RG-217, other high performance
low-loss cables, as will be adapters to HN, N, bulkhead feedthroughs and bulkhead flange totransmission line versions. A hermetic feedthrough for vacuum applications is also being planned.
When 2 BE connectors are mated you have the best available match for your high voltage pulse
system. If your fast pulse rise times are slower than 1ns, you may not benefit much from theadvantages of the Barth BE connectors, but if your pulse rise times are faster than 500ps then you
would see some benefit, and if your rise times are faster than 100ps, the BE connectors are a must.
If your application does not need the wide bandwidth of the BE connectors, just insure that the highvoltage connectors you are using have a cable to connector interface that will handle your highest pulse
voltage pulses. We hope this information will help you to achieve good test results using BE
connectors.

High Voltage Pulse Terminator
ADVANTAGES OVER STANDARD RF TERMINATORS
Low reflection coefficientWithstands high voltage pulses
Pulse power rated
Low voltage coefficientHigh reliability
Impedance held very close to nominal

DESCRIPTION
Barth High Voltage Pulse Terminators are designed to terminate 50 ohm systems with a very low reflection
coefficient. High voltage pulses are terminated with characteristics as good as, or better than, most instrument
loads. These units are ideal for use in nuclear and high energy experiments. Extensive testing during
manufacturing insures very high reliability for single-shot experiments. A voltage coefficient of the resistive film of
less than .0001 %/V allows low voltage calibration of most systems.

High Voltage Pulse Attenuator
DESCRIPTION
Barth High Voltage Pulse Attenuators are matched impedance coaxial attenuators for use primarily in pulsed 50 ohm
systems, or where occasional transients would damage ordinary units. The attenuator design closely matches the
impedance around each resistor, to that resistor. These attenuators feature an input impedance very close to 50
ohms, with characteristics as good or better than most microwave attenuators. These units are ideal for use in nuclear
and high energy experiments. Extensive testing during manufacturing insures very high reliability for single-shot
experiments. A voltage coefficient of the resistive film of less than .0001 %/V allows low voltage calibration of most
systems.

ADVANTAGES OVER STANDARD RF ATTENUATORS
Low reflection coefficientWithstands high voltage pulses
Pulse power rated
Low voltage coefficientHigh reliability
lnput/Output impedance held very close to nominal

MAXIMUM INPUT CONSIDERATIONS
The breakdown limitations of our film resistors are related to pulse energy. A unit that has been rated and tested towithstand 5kV, 400ns FWHM rectangular pulses should be able to withstand 10kV, 75ns FWHM rectangular pulses.
While this general "rule of thumb" has been found useful in practice, we cannot guarantee higher voltages or pulse
widths unless we test the particular unit to your pulse specification.
NOTE: We will only guarantee other voltages and pulse widths or shapes if we life test a unit for that particular pulse
specification.
Our standard units are all 50 ohm impedance. We do, however, manufacture and stock many 100 ohm impedance
units. If we are unable to meet your requirements with a stock unit, call, as other types and impedance's can be
designed to your specifications.

SPECIAL USE CONSIDERATIONS
Attenuators purchased at list price can be used at higher voltages and shorter pulse width ratings but are notguaranteed.
Guaranteed pulse energy performance is available with a nominal additional cost for special testing at specified
voltage & pulse width.

We have found that the best HN Connector pair cannot withstand 25kV at 10ns pulse width for more than 1000 shots. We have tolimit the maximum pulse voltage of any attenuator with HN connectors. They can withstand 25 or 30kV at much shorter pulses.
But we cannot specify what that pulse width limit may be.

DESCRIPTION

The Model 2440 Hand Held, High voltage, High Frequency voltage probe, is intended for passive probing of highspeed, high voltage pulse circuits. The probe kit contains one 450 ohm resistive probe for a 10:1 voltage ratio (20dB),
one 950 ohm resistive probe for a 20:1 voltage ratio (26dB), and one each 450 and 950 ohm replacement resistors.
The probe is designed to have the output terminated into a 50 ohm system. It is intended for output into an attenuatoror 50 ohm scope input. The probe's specified response is for the probe connected with the included low loss coaxial
cable.

Hand Held High Voltage High Frequency Voltage Probe
Model 2440-6GHz
WARNING I SAFETY
The Model 2440 Voltage Probe is designed for the measurement of short high voltage pulses on open transmission
structures in a laboratory environment. General laboratory safety procedures for working on active High Voltage
systems should be followed. Only personnel experienced in the safe operation of high voltage research anddevelopment laboratory type equipment should use this probe.

OPERATION NOTE
Appropriate precautions must be taken to discharge the probe
and connecting cable when the probe is being connected tosensitive sampling scope inputs, because they are very
susceptible to electrostatic damage. Any Teflon dielectriccoaxial cable can easily become statically charged and canhold a charge for a long period of time. Failure to discharge apiece of coax before connecting it to the sensitive scope inputs
can easily damage the expensive front end electronics ofthese sensitive instruments.
The coax cable included with the probe can easily bedischarged from either end by connecting a short or providing a resistive connection from the center conductor to theground conductor.
Touching your finger between the center conductor and outer (ground) conductor on the SMA cable connector is a
simple effective method to remove any charge on the probe cable.
The output of the probe must be connected with the included low loss coaxial cable to a 50 ohm system, for instanceto an attenuator or directly to a 50 ohm scope input. The correct method for holding the probe when making
measurements, is to hold the probe body by the SMA connector in your hand between your thumb and fingers in thesame manner that you would hold a pencil. Placing your hand or fingers closer to the probe tip will add capacitanceto the probe and will degrade the risetime of the probe output. The probe risetime specification includes the use of
the supplied low loss 36" long cable. Use of longer or higher loss cable will degrade the probe's response.

AVERAGE POWER RATING WARNING
The peak, or average power rating, only applies to a well terminated load. Any reflection greater than 10% will
significantly add to the power the DC-20Ghz bandwidth resistor will have to absorb.

Custom High Voltage Probes
For Dedicated Pulse Location Instruments
Output risetime depends on housing construction around these resistors.
When used in the proper/optimum housing, the assembly has <100ps risetime (τ).
The resistors listed here are examples made specifically for fast HV pulse measurement application. They were
designed and tested inside a specific metal housing that accurately simulates their final application use. They arelocated in special gas insulation, HV dielectric material, or were potted in place to provide the required pulse
amplitude and risetime response characteristics. They were constructed to produce repeatable sub-nanosecond
response which requires that the resistor remains attached to the pulse voltage terminal being measured. We
welcome requests for specific pulse voltage measurement applications.
If you have a need for a high voltage probe we can design a specific resistor and housing to fit your requirements.

High Voltage Pulse
Match Resisted Power Divider
Barth High Voltage Resistive Power Dividers are matched impedance coaxial devices for use primarily in pulsed 50
ohm systems, or where occasional transients would damage ordinary units. These units are ideal for use in nuclear
and high energy experiments. These dividers feature input and output impedance very close to 50 ohms. Extensive
testing during manufacturing insures very high reliability for single-shot experiments. A voltage coefficient of theresistive film of less than .0001%/V allows low voltage calibration of most systems.

5081-P Ramp Generator+ 731 3kV Pulse Generator

Ultra Linear Variable dV/dt
Ramp Generator System
Description:
The Barth Model 731 3kV Pulse Generator+ 5081-P Ramp Generator Module
combines our high voltage fast rise time
pulse generator with a multi ramp module
to produce a selectable fixed rate linear
rise ramp pulse.

termination

How It Works
The Barth Model 731 3kV High
Voltage Pulse Generator produces
a fast rise time high voltage
rectangular pulse. This pulse is thenpassed through the Barth 5081-P
Multi Ramp generator module tocreate a linear ramp.
Operation
Quick interactive and intuitive control of
the generator operational parameters
is provided via a touch screeninterface. The test system provides
interactive control of the two variables
that define the dV/dt rate, the pulse
voltage and ramp rate, to achieve
specific kV/us rate pulses. The control
also allows the user to interactively
increase, or decrease the dV/dt rate
which is applied to the DUT.
The 2 basic operational modes are:
The “STP” stepped mode whichfeatures user adjustable voltage and
14 stepped dV/dt selections based on
the 14 fixed ramp rates, and the “VAR”
variable dV/dt mode which features amore continuously variable dV/dt
selectable by the user. This mode isaccomplished by varying the output
voltage within an output voltage range
and jumping to the next ramp selection
as required automatically.

Tem Time Domain Antenna
Model 3400

The Model 3004 is a 50 ohm impedance time domain antenna used to make measurements directly in the time
domain. Use of this antenna for transmitting and receiving allows simple calculations of impulse amplitudes andrisetimes. This "direct" method of measurement avoids the transformation between the frequency and time domains
and minimizes the errors that can arise when basic assumptions are made about a radiating source. We have foundtime domain measurements to be much more reliable when made with this "time domain antenna", to eliminate
frequency domain conversions.
The antenna has a balanced 50 ohms construction to allow maximum bandwidth and minimum reflection, fed with an
integral 50 ohm wide band balun to allow the direct connection between the balanced antenna structure and ordinary
coaxial line.
The good balun prevents off-axis radiation errors from unbalanced currents when used either for transmitting or
receiving. The pulse response between two identical antennas is included below and shows a 75.6 PS. risetime
followed by a slow decay. One antenna was fed with a 50 PS risetime step function of 5 ns. pulse length generated by
our Model 731 reed switch pulse generator fed through low loss BFT4 coax for minimal pulse distortion. The very flat
top from this pulse generator minimizes additional distortion of the antenna pulse decay after the initial rise.
The Model 3004 receiving antenna was fed directly into to a HP 54120A digital sampling oscilloscope through low loss
coax. A pulse response through two antennas was 75.6 ps, or for each antenna an individual risetime of about 53.5
PS. The pulse decay through the pair of antennas to 50% amplitude was about 242 Ps. The antennas were spaced 20
feet apart for this measurement and the pulse response would be slightly better at wider separations.
The antenna framework is 48 inches long by 39 inches wide by 15 inches high. The complete antenna weighs 22
pounds. We are designing some smaller time domain antennas for smaller aperture use, at closer spacings. We arealso designing some larger time domain antennas with higher directivity/gain for use with air propagation or ground
penetrating radar. If you require time domain pulse radiation measurements, our commercial time domain antenna
hardware, high voltage pulse generators, and high voltage pulse experience is available for you.

Our type HN (HNB) connectors are specially designed to obtain minimum reflection coefficient for fast risetimes.
For best pulse response, our Model 401-HNB male or Model 402-HNB female cable connector for RG214/U
coax should be used for interconnection, available in our Pulse Catalog. Unit is supplied with a Barth Model
404-HMM low reflection male to male adapter, so that either the input or output can be adapted to a maleconnection.
**

BNC female tap off output is optionally available.
