Ah, I see.
device (that you mentioned) does what you need, but the GPIB address is set by the instrument and unfortunately it is fixed as 1, so that limits you to a single device having this limitation.
I can see a couple of solutions. But none are easy:
- Alter your software to be able to handle USB devices (going forward this might be the best approach)
- Have multiple GPIB bus devices and place one Tektronics scope on each
- Create some clever hardware to fit inline with the USB and alter the address that it uses.
- Create some clever hardware to fit inline with the GPIB bus to alter the address that the converter has.
In terms of hardware (i.e. between 3 and 4), I think that (4) is probably the easiest, but it would take a lot of experimenting and knowledge of GPIB to get it working.
) is a description of a USB to GPIB adapter (the opposite of what you need). It links to all the data required to make one. I can see no reason why you couldn't have 2 GPIB interfaces and translate between them, simply changing requests for address 10 to requests for address 1 (for example). [I can't see any reason, but I'm no expert]
As has been noted
"there's no hacker demand for these, so they can be quite pricey".
