*IDN? problem with panametrics 5900pr

[raymond cwf]

i want to use GPIB-USB-HS to connect the panametrics 5900pr to my computer. then i use MAX and scan the instrument and the problem comes out. the description show "the device did not respond to a *IDN? query." should i need to have some setting in the GPIB config or something else? anyone can help me? thx..

Are you sure the GPIB address is correct? Did you perform a "scan for instruments" on GPIB bus, in order to verify whether the instrument is accessible?

Did you use the same interface on some other instrument before?

Just trying to figure out what's wrong...

There's probably nothing wrong. Check the manual to see if it supports the *IDN? command. If it doesn't (i.e. if it's an old onstrument), then ignore the warning in MAX. It's been detected as being there.

i have checked the manual. the command should be *IDN. I try this command but no response...i try other commands, also no response. what can i do?

Taking a look at the driver for the 5800, each command has a CR appended to it. This is not quite 488.2 compliant but fairly common to older instruments. Verify this in the manual and try sending a CR (\r in MAX or with '\' Codes Display on) and see if that works.

I would recomend you download the 5800 driver as a starting point for your code - assuming you are using LabVIEW of course.
