LIV testing is a key step in determining the functionality of laser diodes, LEDs and LIDARs.
Pulsed Sweep
With pulsed sweeps, the current amplitude is increased in steps and voltage or other measurements are made at each step. With pulsed sweeps, device heating is reduced and cumulative heating may be avoided. With pulsed sweeps, high power devices may be tested without the need for active cooling.

Python API and Examples
Python API and examples allow you to worry less about the code and more about the science of LED and Laser testing. Vektrex offers many options to quickly automate testing of LEDs and Lasers.

SpikeSafe Source Measure Unit
The SpikeSafe SMU is a precision pulsed source measure unit that precisely sources pulsed current and simultaneously digitizes voltage. Optimized for precise and repeatable high-power LED and laser testing, SpikeSafe™ SMU (Source Measure Unit) current sources deliver precise pulsing with low microsecond rise times, low-jitter triggering and integrated digitizer for more accurate and repeatable high-power LED and laser testing.
