Has anyone had any luck with interfacing with MicroTest devices via LabVIEW? I'm not seeing any official drivers, which is unfortunate.
Specifically I've been looking at the 6630 and 6632: MICROTEST | Precision LCR Meter
They claim USB/LAN/RS-232 communication for automation, so it should be doable, but I'd feel a lot more comfortable if someone had had experience with them.

Well when it comes down to it the vast majority of "official drivers" are just the instruments SCPI commands that someone has done all the grunt work and written a set of basic VIs that fit the NI Instrument Driver guidelines.
I didn't see a manual available for download, but I am guessing that it has all the SCPI commands in it.
Those SCPI commands and NI-VISA is all you should need.

While it doesn't mention it in the text, looking at the pictures of it show a GPIB port on the back of the device. GPIB support 99%+ of the time means that commands are in plain ASCII (SCPI).
However the only real way to know is to contact them directly as they don't have a manual available to show the commands on their web site. You could also ask them if they have example code, whether it's LabVIEW or not, as a starter for any drivers you may need to make yourself.

It is indeed common SCPI commands, and you should be able to implement them in LabVIEW
