Great work making this available for sale. NI and Keysight are the only two traditional vendors of this kind of thing and they’re priced close to $1k these days. There are tons of knock-offs on Ebay that won’t last more than a few months if they ever work.

used NI-GPIB on USB cost $100 on ebay. You don’t need $1000.

FWIW, You can buy legit used 82357s for quite a bit less than 1k. Anecdotally, I've never had one fail in 20 years. Probably bought a dozen over that time frame. All used daily.

Even worse, the windows drivers know they're knock offs and let you use them for a bit and then error out. It's the perfect lesson. They give you that high of "yes, I got one over on the big guys, we're cruising now" and then "I don't know boss it's just all of a sudden not working anymore. Yes I know we're in a production crunch. Yes we should've just bought the real one". On Linux though, no issues for me

Yes, it is easier to fall into the trap of getting a clone, even if you think you buy an original one.
