Continuous Pulse Mode
In addition to LIV characterization, laser diodes typically require some type of wavelength or spectrum measurement.
In these cases, the 2520 can be used as a current pulse generator, driving the laser diode with a current pulse train
while a spectrometer or other instrument makes measurements. As a pulse generator, the 2520 provides a fixed pulse
current level with control over pulse width and pulse off time to provide a desired duty cycle. As with conventional,
single purpose pulse generators, no measurements are made when using the 2520 in the continuous pulse mode.
Ensure that the 2520 is using the latest firmware, B06 as of this writing, before using the continuous pulse mode.
