Rj-7600
Energy Meter
MeterSeries Energy
The Rj-7600 Series Energy Meters work with avariety of probes - pyroelectric, silicon, andthermopile - to measure true energy per pulse
from single-shot to 40 Hz, picojoules to Joules,
UV to far-IR. Sets of 10 or 100 pulses can bestatistically analyzed, and data can be transferred
to computer via the IEEE-488 GPIB computerinterface. The Rj-7620 Dual-Channel Energy
Meter accepts two probes and simultaneously
displays the energy incident on Channels A and B,
as well as the ratio of Channel B/Channel A.

The Rj-7600 Series Energy Meters feature a highcontrast, backlit, alphanumeric LCD display,dual-use numeric/function keys, and powerswitch. The default display mode continuously
shows the Channel A energy per pulse, thenumber of pulses to be averaged (1, 10, or 100), a
running counter of the number of events elapsedin the current pulse set (10 and 100 events only),
and whether the instrument is in Local or Remotemode. In addition to this the Rj-7620 Dual
Channel Energy Meter also displays the Channel
B energy per pulse and the energy ratio (B/A).
When Averaging is set to 10 or 100 events theMODE key toggles the LCD between the threeavailable displays: default, minimum andmaximum energy (Channel A for Rj-7610; A and
B for Rj-7620), and standard deviation (ChannelA for Rj-7610; A and B for Rj-7620).
The Rj-7600 can be operated in Single Event(capture-and-hold) mode. When armed, theinstrument will capture and display the energy
recorded at the first trigger, and ignore all
subsequent triggers until the instrument isrearmed or the feature disabled.

Rear panel connectors include the power entry module;
Probe(s); GPIB; Sync In; Analog Out (Rj-7610); Ratio
Out, A Out, and B Out (Rj-7620). The power entry
module accepts a standard line cord and has aswitchable 110/220 VAC card. The Sync In BNC
accepts an external TTL trigger pulse for syncing theinstrument to an external source (a laser trigger circuit,for example).

The Analog Out on the Rj-7610 is a 0-10 VDC signal
where 10 V corresponds to full scale. The Analog Out
updates with every trigger. The Ratio Out for the Rj7620 is similar to the Rj-7610's Analog Out, except it
can be toggled via the MODE function to selectChannel A, Channel B, or the B/A Ratio. When B/A isselected the voltage corresponds to the mantissa of theratio. The Rj-7620 has two additional outputs, A Out
and B Out, that show the post-preamplifier waveform,
whose baseline-to-peak voltage is proportional to thepulse energy.
The IEEE-488 GPIB computer interface outputs thefollowing information in ASCII format, in real time up to40 Hz, for Channel A (and B for the Rj-7620): pulse
energy in scientific notation, min & max energy, andstandard deviation. Ratio B/A is also available (Rj-7620
only). Any combination of these can be enabled ordisabled for transmission.
The Rj-7600 Series instruments are compatible with theRjP-700 and RjT Series probes. Contact the factory for
additional information regarding probe compatibility
and available options.
The Rj-7600 Series instruments are provided with acertificate of calibration showing traceability to theNational Institute of Standards and Technology (NIST)
and compliance with MIL-45662 and ANSI-Z540
Sections 7-18.

SPECIFICATIONSA Calibration Factor for each channel can be entered
via the numeric keypad to compensate for non-linearity
in the optical path - for example, transmission loss
through a filter, or the spectral response of a non-flat
detector. The measured energy is divided by theCalibration Factor and the corrected energy displayed.
