Hi,

I have a Keithley 4200-SCS connected to my machine via an NI USB/GPIB interface. I also have the newest version of Matlab (2022a).

The visadevlist command does not populate with my device.

I have the NI Max software installed and can communicate via the NI VISA > VISA Interactive Control, by manually inputting commands. I was also able to communicate just fine with the older gpib functions over Matlab, but since they are being deprecated, I was hoping to switch over to the newer visadev commands.

I think the issue is that the Keithley 4200-SCS has it's own older command set instead of the 'newer' standard SCPI command set. When I run the visadevlist command, I see on the keithley that it got an '*IDN?' command, but it errors out since that's not a command it knows; It instead uses the 'ID' command.

Thanks for all the help.
