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?


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%:

* Which GPIB adaptor do you use?


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.
