Title: Correct GPIB-Commands to control a Keithley 705 Scanner-Mainframe?
Post by: Echo88 on January 28, 2018, 12:24:56 am

Seems im too dumb or blind to find the correct GPIB-commands to simply activate/deactivate channels of an arbitrary relay-card (i have a Keithley 7059-card plugged in, which are just 10 relays). Maybe someone can help me out with a working example?

Keithley 705 Manual: https://doc.xdevs.com/doc/Keithley/705/705_901_01F.pdf

Thanks.

I haven't used that unit, but it from reading the manual, something like C002 X should close channel 2. Depending on the type of card, you may need to open the previous channel manually unless you use the built-in step / scan feature. X stands for execute the previous commands in many Keithley instruments from this era.

Thanks! "C002X" or "C002 X" did indeed work. After a little manual-reading ive also seen that "N002X" is the correct command to open the channel.
I was just confused at first that "C002" wouldnt work and didnt see that the "X"-suffix was needed to execute the command.

On page 49 of the manual is a fitting program example which i didnt see at first.
