Hmmmm... How are you connecting to your instrument? Serial
or GPIB? What is the address of your device? What address
are you using? If all cables are securely connected, and you have
verified that the address of the device is the same one you are using
in software, then we should go into Measurement and Automation Explorer
(MAX) and see what we can do there.
Once in MAX, if you are communicating via serial, right click the
serial port you are using and choose to "Open VISA Session".
There should be a Basic IO tab. Use that to do Writes and Reads.
If you are using GPIB, first select your GPIB interface, then scan for
instruments. If your device is connected correctly, and is SCPI
compliant, the scan should find your device. You can then right
click on the device listing and choose to "Communicate with Device" and
do queries, reads, and writes.
Once you have been successful in communicating with your device, verify
that the name of the device in MAX (ASRLx::INSTR or GPIBx::y::INSTR) is
the same name that is being used in LabVIEW.
Hopefully this helps. Good luck!
