I'm making my own pyvisa driver for some P9371A VNAs we recently purchased.
The help file indicates in at least one place that there is no good way to turn channels on and off with SCPI commands(note None in table below copied from help file):
|Channel 1 - 8 Tab Commands|
Are there any plans to update this SCPI functionality? It seems like channels are close to unusable with SCPI. But yet, quite a few commands take cnum (channel number) as a parameter.
As a work-around, it looks like I could abandon channels altogether and instead manipulate traces and windows. But even that does not seem to be as straightforward as one might hope...
