LIV Testing

LIV testing is a key step in determining the functionality of laser diodes, LEDs and LIDARs.

Staircase Sweep

Staircase sweeps, also know as Integrated Pulsed Sweeps, are a traditional method for generating an I-V plot. In a staircase sweep, the current level is increased in steps, and measurements are made at each step.
