read two keithley 2000s simultaneously

[wjstraka]

Hey,

     I am trying to read DC voltages across two Keithley 2000s simultaneously. As it stands right now, I have simply initialized both Keithleys, set them both up to read DC Voltage, wait for a trigger on the front panel (a simple OK button), read the data and write it to an array. Afterwards, the data from the array is written to a text file. The problem is, the voltages are being read one after another instead of at the same time. How do I fix my code or what else do I need to make this happen? I have attached my code thus far. Thanks.

You can't do a simultaneous read. You have to trigger both instruments at the same time. Then do the sequential read.
