    Linux gpib also supports my adapter natively with a special linux gpib firmware you can download from the page above. It also supports multiple instruments connected to one adapter…

    Works even well on Mac and Raspberry PI btw :-) Actually world would need an open source visa stack. Right now you find many applications doing their own thing, but then not suppor…

    As I have a CMU200 myself I was majorly interested in getting it to work too :-)

    I know that very well. Ethernet=security concern. Connecting your shiny new scope to company network=no way. Hard to discuss arround it in company environments or push for split ne…

    Yes, those cables are often called "garden hose cables". The only benefit of that bus infrastructure under a nowadays view is that it gives the ability to synchronously trigger mul…

    The step to go to ARM or risc v based controllers is easy. That's what I did with V3. Gives a tremendous performance boost and costs 1/2 of that old AVR.

    A good way around application overloaded applocation stacks is R&S Visa which is lean and mean while still exposing full visa to applocations like labview. Or going with something …

    For a situation where the instrument is directly connected to the adapter like here there is no difficulty in fast T1 timing on a MCU. V3 will have btw. fully compliant GPIB electr…

    The upcoming V3 adapter reaches even more than 1 MByte/s with my fastest instruments. Unless you connect long GPIB cables to it, because capacitive load slows down GPIB as it self …

    If you buy used equipment which doesn't have Ethernet or your company wants you to ise the stuff that is in the Lab since 10+ years there's simply no other choice. Or companies tha…

    You are correct. UsbTmc exposes no multi device capability. Also when I made first versions many years ago I had no "garden hose" GPIB cables and saw they were more expensive as th…
