GPIB clones, TMC, compatibility issues

[wa1hco]

I really like the look of the HP8753-Companion software and need it's ability to work with the calibration data. But... The USB - GPIB interfaces that are available for ~$50 appear to be clones of NI-USB-HS and don't really work under Linux as far as I can tell. There is a USB - TMC interface designed for Linux that does work (as far as I can tell).

Is there a way to adapt from usbtmc to GPIB or is it possible to adapt HP8753-Companion from GPIB to TMC?

How would TMC help here? The 8753 is GPIB only.
I've used what I am sure is a clone Agilent 82357B controller with linux gpib without problems.
I have also a NI USB-B controller that I suspect is fake (although the NI software says is genuine) that works.

The usbtmc project creates the tmc interface with an mcu on a gpib connector. As far as I know it's almost impossible to find a working usb-gpib adapter. My ni-usb_hs throws unexpected byte messages on plugin. Some say it works anyway, but not for me. But, I've never gotten any of these combos to work, so little experience. The usb gpib folks seem to say the clones are not supportable. Maybe the right stack for linux is gpib instrument, tmc to usb adapter, ni-visa, then the application with visa interface. Repeating...definitely not very knowledgeable, just getting more old test equipment. Jeff

Is this what you are talking about ... https://github.com/xyphro/UsbGpib?
If so, yes such an accommodation could be made but I don't have one of these and thus cannot develop or test such an interface.

Can send you one or more, built 5 Jeff

OK, I'll give it a go .. it will probably take some time. Do you know if this device handles GPIB SRQ interrupts correctly? (that would probably be the only tricky thing. The rest are just standard read and write commands.). I'm in the FCC database (NV3Z).

SRQ handled correctly? Can't say, but the comments indicate some care taken with respect to various ways VISA handles it. Package in the mail tomorrow, US Postal Service 9200190347375204691390. thanks, jeff
