Re: [Linux-gpib-general] Using Linux-GPIB in raw mode to log GPIB Data?

[Anders G. <And...@pe...>]

OK. Yes. I know about the NI Analyser, but I have yet been unable to find out what memory depth it supports. I
know that some chips have a passthrough register that lets you sample the bus, but then again could you just
as easily use the parallell port, but the problem there is reading it fast enough.

Linux-gpib doesn't support bus analyzer features.  The NI gpib-usb-hs+
has bus analyzer features but I never bothered to reverse engineer how
the protocol works.  Most gpib chips (nec7210 etc) do not allow you to
capture every command byte.
