vrf Filter/intercept GPIB commands

Question asked by VRFuser on Dec 4, 2007
Thanx for your ideas!

Indeed, it would be more consistent to get the vendor to change the automation, unfortunately it sometimes takes a while until new SW version are released, and sometimes different DUT's behave different for the same automation scenario.

Anyway, it seems like there is no such solution made already and I cannot spend the time to build a wrapper at this point. I was hoping someone may have done something already in this direction or that there actually are already functions in visa that I just don't know about.

Thanx again for brainstorming!

Robert

I did something similar to that a ways back with SICL, so I'd expect that something similar could be done with VISA.

Ended up creating library that duplicated the SICL commands and looked externally like SICL. It internally did SICL calls to the "real" SICL library.

I would think that you could write a VISA lookalike and have it call the "real" VISA.

Woudln't it maybe be easier to get the vendor to fix their code?
