2461 SourceMeter pulse train clipping at 36 V short of 105 V spec
I am trying to set up a test where I am looking for short low current voltage pulses out of the 2461 SourceMeter. To verify the test pulse out of the unit, I have tried to measure the pulse train by connecting the oscilloscope directly to the output of the 2461 (FORCE HI/LO) and through a 1 Mohm resistor. As I increase the voltage set point of the pulse train, the output begins to clip at ~36 V, far short of the target/spec of 105 V. Is there an obvious reason why the output may be clipping at 36 V? I have tried different combinations of pulse widths and duty cycles that all resulted at the same clipping point.
