Multiple VISAs on the same computer
Rax:
Hi all,
A while ago I managed - with help from this community - to get going a xyphro USB-GPIB adapter by, among other things, installing the R&S VISA package (in hindsight, I should have done the Keysight or NI package...).
I'm now trying to start using an NI adapter (GPIB-USB-A). I assume I may only need the drivers part of the NI package (which seems massive), but leaving that aside for a moment, the NI package seems to need to install its own VISA (which makes complete sense). In doing so, it's finding the R&S VISA present, and it wants to rename it.
Any recommendations? I'm concerned I'll lose the ability to use my xyphro adapter. But if not too difficult, I'd rather replace the R&S VISA, as I don't estimate I'll ever need to control an R&S instrument at my bench.
Thank you all for your insight.

xyphro USB-GPIB adapter is usbtmc based interface, it is not a pure Visa interface, i have such an adapter and RS Visa works fine for me
i dont mix Ni or Keysight librairies, but RS visa let you choose the driver you want ...
but if you have usb or lan interfaces on your instrument i would switch over them ...

coromonadalix,
If I follow your point, it seems to me you're saying I should be able to run the NI GPIB-USB-A with the R&S VISA package, by only getting specific drivers installed? If yes, could you please elaborate on that solution?
I only have two choices for interfaces with the instruments, both GPIB to USB. Ideally, I'd run everything over wifi (my whole house is between my modem/router/server and the bench). But I think that's a whole other proposition, so I don't think I can currently go that way. Unless there's some simple and affordable solutions I'm not aware of.

I have both R&S VISA and NI VISA installed on the same machine, mostly to use NI USB-GPIB adapters. Have never had an issue: just did the default install for both and everything worked with no additional install, tweaking, etc.

Can you share more details, if a recent installation? For instance, having already installed the R&S VISA package (for the purpose of making a xyphro USB-GPIB work, which it did), when I try installing the NI at this later time, it's trying to rename the R&S (quoting the warning from memory). Have you had this happen? If yes, was it harmless to devices using the R&S VISA?
I'm curious if, for instance, in my case, allowing for this renaming during the ulterior NI install to happen would effectively switch over the default VISA for the xyphro to the NI (which, if the xyphro continues working undisturbed, I'd not mind at all).
