Testing Laser Diodes
NI recommends that you calibrate the responsivity and dark current of the external photodetector (ePD) before testing an LD and fill in the values of the PD responsivity and PD dark current parameters

The Model 2520 provides all sourcing and measurement capabilities needed for pulsed and continuous LIV (light-currentvoltage) testing of laser diodes in one compact, half-rack instrument.
Testing a laser diode properly requires a current pulse of the right shape. It should reach full current fairly quickly (but not so fast that it causes overshoot and ringing), then stay flat long enough to
