I have questions like:

* The 3586 manual says in one place that the frequency increase/decrease
buttons do not function in the remote mode. In the chart of commands, it
says that the GPIB command for increase is UP and the GPIB command for
decrease is DN. Does anyone know whether these are valid commands or not?

* Can anyone provide a step-by-step procedure for the command sequence to
read the 3586 signal magnitude using GPIB?

* Which GPIB adaptor do you use?

Many thanks.

Cheers,
John - KD5YI

No idea, but why not just try it out? In case you don't have all the
manuals they can be found here, scroll down about 40%:

The Prologix USB. Works fine (after finding a level threshold bug and
the designer made new firmware for it).

Hi, Joerg -

I was using a Softmark USB-GPIB unit. Although they responded to commands, I
spent about 20 hours trying to get a reply other than gibberish from three
different instruments with no success. I may have to roll my own controller,
but first I have to understand GPIB.

Thanks for the link, but I already have the manuals. It is the operator's
manual that I referred to above when I pointed out what I think is a
contradiction.

73,
John

That's what I had at first as well, just gibberish. Turned out the logic
threshold is way too high in the Prologix. Engaging the internal
pull-ups of the uC in there did the trick.

I'm glad you got them to fix it because I ordered a Prologix one yesterday.
I think I should have gotten the Prologix to begin with because I need to
write my own software to do things and the Softmark was not set up for that.

If you run into issues and think it's related to the Prologix design
just write to the designer (Abdul). He is very responsive and actually
the firmware you are getting with the new one will reflect the Vt change
he and I found necessary. All others with older versions can just
download the new firmware from the Prologix site.

I guess you've already found this site but just in case others here have
not, this is a great tool set for GPIB:

Except for those of us with the first-generation Prologix product,
alas. It has a different architecture, and (as far as I can tell) no
upgrade path available.

It works reasonably well with my Tek scope, as long as I'm careful
with the command sequences and don't ask the scope to send any data
back in binary mode.

I got it today and it works very well. I had it talking and listening to all
three of the GPIB-capable instruments I have in less than an hour.

Thanks for the link.

Great! Yours is probably screaming-yellow, mine's the now ancient silver
version. I still have to make angles for the GPIB side from Digikey
connectors and some ribbon cable. The Prologix plus USB cable sticks out
too much towards the back, easy to crush when moving an older analyzer.
