Measuring 4132 during 4139 Current Pulse

[KVS2]

I am using a 4132 (Gate) and a 4139 (drain in pulsed mode) to measure an FET.  I need to measure both SMUs during the 4139 pulse.  I am using the attached VI , but keep getting a Error -1074118620 occurred at FetchMultiple.VI.  Is this a trigger issue or timeout issue?

It looks like that error is returned when there are no samples in the buffer to fetch from.  It seems like the device has not received its start trigger so the device hasn't started to collect any samples before the fetch VI times out.  You can try manually selecting the terminal to trigger from instead of building the terminal through the build terminal VI.  You can also troubleshoot by selecting no trigger and see if the device fetches successfully.
