GPIB/IEEE-488 interface

The LDX-3200 Series Precision Laser Diode Drivers area best-in-class family of high precision microprocessor-based
instruments that offer a high stability, low noise current sourcewith integrated laser diode protection circuits, specifically forcontrolling laser diodes. These laser diode drivers are known
throughout the industry for their reliability, precision, and easeof-use.
The LDX-3200 Series consists of three family memberswith current ranges of 50/100mA (LDX-3210), 200/500mA(LDX-3220), and 2A/4A (LDX-3232) covering a wide range oflaser diode testing and control applications. The LDX-3232 wasdeveloped for controlling high compliance voltage devices suchas quantum cascade laser diodes with the same low noise,high stability performance of the series. In addition to precision
current control, the LDX-3200 Series products are loaded withstandard features such as dual current ranges, constant power
control, fine/coarse set point control, four-wire forward voltage
measurement, and external modulation capability.
All of ILX Lightwave’s proven laser diode protection strategies
including adjustable current and voltage limits, intermittent
contact protection, and output shorting relays are designed into
each driver. For automated testing applications in an R&D or
production environment, remote operation is easily accomplishedthrough the GPIB-IEEE-488 interface. For virtual instrument
programming, LabVIEW® instrument drivers are available on
our website.

PRECISION HIGH STABILITY, LOW NOISELASER CONTROL
Laser diodes act as a gain medium. Small drive
current fluctuations due to noise and drift are amplified
optically. Because of this, a controller with a lower
noise and stable output is required to ensure precise
wavelength and power control.
Each LDX-3200 Current Source offers digital 16-bit
control and measurement allowing setpoint accuraciesof +0.05%. Careful attention to design delivers source
stability as low as 10ppm with low noise for precise
control of laser diodes.

A CHOICE OF LASER CURRENTCONTROL MODES
Each laser diode driver’s laser current source can be
operated in one of three modes:
1. Constant current, low bandwidth
2. Constant optical power
3. Constant current, high bandwidth
The constant current, low bandwidth mode is optimized
for DC operation and offers improved laser protection
and lowest noise.
In constant current, high bandwidth mode, the output
stage supports up to 1MHz modulation frequency for
dithering the laser current in power and wavelengthtuning applications. For laser protection, the modulation
signal is implemented as a differential input, allowing
the modulation control voltage and laser outputs to use
different grounds.
The constant power mode provides constant opticalpower operation of your laser diode by measuring thephotocurrent from the laser diode’s rear-facet photodiodeor an external photodiode in a feedback control loop to
the current source.

SETTING THE STANDARD IN LASERDIODE PROTECTIONILX Lightwave’s internal testing and protection
standards ensure protection for your laser diode underabnormal operating conditions such as intermittent
contact or severe power spikes. These standards
have led to advanced protection features like clamping

LDX
3200
Seriescurrent limits, even under modulated conditions. In
addition, exclusive braid-shielded cables have been
specifically designed to suppress radiated noise andtransients commonly found in laboratory or production
environments.
During AC power-up, careful turn-on sequencing andredundant output shorting circuits protect the laserfrom current transients. when the output is enabled,
the slow-start circuit gradually opens the shorting
circuits. Current is shunted through the shorting
switch until the control circuits are fully active and all
circuit transients have died out.

PrecisionLaser Diode
Drivers

A feature not found in most laser diode drivers- fast output shutoff - provides an additional level ofprotection from intermittent contacts between thelaser diode and the current source.
These protection features all work in conjunction withall instrument modes of operation, providing worryfree, fail-safe control of your laser diode.

EASE OF OPERATION
The front panel of the LDX-3200 Series Laser Diode
Driver offers quick, easy operation and information
display without confusing multi-layer menus. A bright,
5-digit, green LED display is easy to read from a
distance, even with laser safety eyewear. Laser
control is directly addressable from the front panel“adjust” section including a “fine adjustment” function
for more precise control for sensitive operating
parameters. Instrument parameters and modes
are easily selected or adjusted through discrete
pushbuttons and a rotary digital encoder.
For automated testing or control applications, remote
programming and control of the driver is easily
accomplished through the GPIB/IEEE-488 interface.
All driver functions are accessible through theinterface bus, with commands based on a set of easyto-use mnemonics. Higher resolution measurementsof current and voltage are also available through the
GPIB interface.
The LDX-3200 Series architecture simplifies routine
maintenance. Closed-case calibration can be
performed from the front panel or the GPIB interface.
The instrument is placed in calibration mode througha unique combination of front panel push buttonpresses or GPIB commands.

LDX-3200 Series Laser Diode Drivers can be analog modulatedwith an external input to 1MHz.

GPIB/IEEE-488 interface

The LDX-3200 Series Precision Laser Diode Drivers area best-in-class family of high precision microprocessor-based
instruments that offer a high stability, low noise current sourcewith integrated laser diode protection circuits, specifically forcontrolling laser diodes. These laser diode drivers are known
throughout the industry for their reliability, precision, and easeof-use.
The LDX-3200 Series consists of three family memberswith current ranges of 50/100mA (LDX-3210), 200/500mA(LDX-3220), and 2A/4A (LDX-3232) covering a wide range oflaser diode testing and control applications. The LDX-3232 wasdeveloped for controlling high compliance voltage devices suchas quantum cascade laser diodes with the same low noise,high stability performance of the series. In addition to precision
current control, the LDX-3200 Series products are loaded withstandard features such as dual current ranges, constant power
control, fine/coarse set point control, four-wire forward voltage
measurement, and external modulation capability.
All of ILX Lightwave’s proven laser diode protection strategies
including adjustable current and voltage limits, intermittent
contact protection, and output shorting relays are designed into
each driver. For automated testing applications in an R&D or
production environment, remote operation is easily accomplishedthrough the GPIB-IEEE-488 interface. For virtual instrument
programming, LabVIEW® instrument drivers are available on
our website.

All values relate to a one-hour warm-up period.
Over any one-hour period, half-scale output.
Over any 24-hour period, half-scale output.
Measured optically, evaluating noise intensity of a laser diode into a 150kHz bandwidth photodetector. LDX-3210 and LDX-3220 only. See the LDX-3232
product brochure for further information.
Maximum output current transient resulting from normal operational situations (e.g. power on-off and current on-off) as well as accidental situations (e.g.
power line plug removal).
Maximum output current transient resulting from a 1000V power-line transient spike. Tested to ILX Lightwave Technical Standard #LDC-00196. Request or
download ILX Application Note #3.
Maximum monitor photodiode current drift over any 30-minute period. Assumes zero drift in photodiode responsivity.
50% modulation at mid-scale output. Higher bandwidth is possible with smaller magnitude modulation signal.
Small signal specification is for typical 10% modulation depth. Large signal specification assumes 50% modulation depth at mid-scale output.
The responsivity value is user-defined and is used to calculate the optical power.
Four wire voltage measurement at the load. Voltage measurement accuracy while driving calibration load. Accuracy is dependent upon load and cable used.

In keeping with our commitment to continuing improvement, ILX Lightwave reserves the right to change specifications without notice or liability for such changes.
