Figure1 Output current with the SCAN function
For LDC500 series laser diode controllers, the output current shown in Figure.1. CH2 (red trace)
SCAN command can be used to initiate an automated shows the laser current output starting from 25mA,
sweep of the laser operating point. For example, in then 125mA, through 325mA in 3 steps. The time
Constant Current mode, we set initial laser current interval of each step is 50ms. CH1 (blue race) shows
