Hi,
I'm very new to all this so apologies if this is a useless question!
I'm trying to use the Keithley 2450 to continuously supply a voltage and once externally triggered, rapidly sample small currents till the next trigger. It should then transfer the buffered data and do this in a loop. The trigger is a 1kHz pulse signal and ideally it should start sampling on the falling edge and stop on the rising edge(i can introduce delays to fix that if need be) . The current is around 100 nA, and i don't need auto-range or auto-zero, just as fast a measurement as possible in the 900 uS between the two pulses.
So the questions i have are;
Can the 2450 sample that quickly?
What would be the easiest way to program/script that can run this scheme. I've never used GPIB commands or Visa before but willing to learn!

Hey zzims,
Are you using the Keithley driver?
