HP 8563A Spectrum Analyzer not recognised by gpib?

[AD_7777]

I recently installed a Gpib board in my computer, and tried to communicate with a Hp 8563A spectrum analyser and luck, it says i dosen't recognised the *Idn? command, but our Giga-tronic does

Did you look in the manual to see whether the instrument even supports the command? If it does not, then just ignore the warning.

We have an 8561 in our lab. Same series. I can confirm it does not implement the *IDN? command. Instead, it uses the ID? command. These instruments are really old, and I think their command implementations were done prior to the accepted conventions of the so-called "standard/common" GPIB commands, so vendors made up their own commands.

Do you which driver you use in Labview for that model?

I didn't. For the few commands I needed at the time I just implemented them directly. IDNET does not have a driver for that specific model, but there may be one there that's for a similar model that has a similar command set.
