Hello,
I'm trying to use a 3458A and 3457A via GPIB with the latest version of Keysight Instrument Control and a genuine 82357B USB adapter.
I would like to mention that all functions work with a 34401A, so it's likely not a defective 82357B USB adapter / corrupt software install.
The problem that I am having is that I can't read any data from the 3458A and 3457A. When I try to send a command that returns data (such as ID?) the read times out.
Non-read commands such as "DCV", "DCI", "ACV" work as expected. The instruments do get detected by the adapter, and I can see them and they show up with the correct address.
Any idea what could be the issue ? I'm assuming there are some configuration options for the USB adapter that I have to set in order to get it to work with older HP gear, but I can't seem to be able to find them.
I tried turning off auto-device recognition via the "*IDN?" command but that did not help.
The screenshot below shows the 3458A and 3457A connected.
Any tips ?
Thanks!
