7011 sequencal switching

Post by olorin17 » May 29th, 2014, 4:13 pm

Hello everyone! I am trying to get the Keithley 7001, with a 7011c card to open and close channels in sequence. I.E. close @1!1, open @1!1, close @1!2, open @1!2, but in sequence, NOT all at once. I am able to open and channels with the SCPI commands individually, but i need it to operate all as one big program. can anyone give me a hand? i am not even sure where to start.

thanks in advance!

What you are referring to is a "scan".
Simply set up a scan list with the following command.

:ROUTE:SCAN (@1!1:1!40)

Then set up the trigger count for the number of channels.

:TRIGGER:COUNT 40

This will go through all 40 channels one time when the appropriate trigger is received.
