I'm trying to take a pulsed measurement off an N1912A with an N1921A sensor using automated code in MATLAB. I'm injecting a sequence of pulses into the meter. I'm interesting in capturing information on the last pulse in the sequence. I have the power meter setup to use an internal trigger in continuous trigger mode. My questions:
1. How fast does the N1912A / N1921A trigger? For example, if I send a new pulse every 1 millisecond, is the meter guaranteed to trigger off each pulse?
2. After the sequence of pulses finishes, I have to first turn off continuous trigger mode in order to query information off the meter. Afterwards, I am able to pull trace data, but I can't seem to successfully pull the measured power using the FETCH command. I'm guessing that this has something to do with that data being cleared from memory somehow, perhaps related to using continuous trigger mode? I can provide code examples if necessary.
