I am trying to use TSP Express on 2651A to measure a power diode forward curve. My problem is that my measured data looks correct with DC sweep, but when I try to use Pulse mode I saw a great difference between source voltage and measured voltage. For example when I sweep from 0V to 3V the measured voltage only went from 0V to 1.2~V. My current limit was set to 10A and the measured data at 3V source output (which is 1.2~V measured) is 4.5A.
I also couldn't get reasonable result with pulse mode if I didn't set a user defined measurement delay. I am suspecting that I am not fully understanding the measurement point within each pulse. Is it possible that the measurement is done outside of the pulse stimulus event?
