I would like to know the difference between 82357A and -B.
The reason is that I will try to use the maintenance software for E44xx -B signal generators, and the prerequisites states that this software requires the -A version...
I'd imagine the B version is simply a later version, maybe with some subtle hardware or firmware changes. I had a quick look at the manuals for the instruments but I couldn't find any reference to the card version. I would just try it with the B version - either it will run as expected or ( and I think this is very unlikley ) you'll get some inexplicable bug at some point: if the latter, at least you know that it could be an interface card version issue.
I own both Versions. A is the elder one, no longer produced.
B is the newer one.
They should work in same way, But A versions works under windows2000, and B version not ;-)
So just use the B as you only can buy this from keysight.
