Can't get Measurement & Automation to list equipment NI Spy says it sees.

[BCLioness]

If I have the HP4083A on the network, none of the other instruments get listed in M & A. BUT without the 4083, all other equipment is listed correctly. IBIC lets me talk to the 4083 and idn? gets a response, but no other commands seem to work.

This must be a pretty old box. I can't find any mention of it on Agilent's web site and there is no driver for it from NI. Can you describe what it is? Is it possible it has the same address as another instrument? Can it act as a bus controller? What do you get back when you do the IDN?

It is a switching controller. I am trying to set up an old semiconductor test stand that has this in it. I am told it is used to set up for testing current or voltage. I too had looked for drivers and I have a query into Agilent to see what they think, but no response yet. The address is definately not the same, in IBIC I listed all the equipment hooked up, and they all matched what I expected, no repeat of address.

Sorry, didn't answer all your questions. As far as I know, it cannot act as a bus controller and idn? gives " C 0 0 0... ", or " I 0 0 0..." depending on whether I have voltage or current chosen, which I have to do manually as I cannot yet control the current/voltage switch even through IBIC.

About all I can say is that's the most unusual response to IDN? that I've ever seen. Normally, an instrument would come back with a string with it's model number and not it's settings. Sorry I can't help. Maybe you could try posting to the GPIB and Instrument Driver forums and see if anyone there has experience with this thing.

OK, thank you for your help.
