Yeah *IDN? should return the model, hardware revision & software revision (IIRC). If your transaction looks like this you're doing it right:


If that produces problems check your baud rate, handshake, bla bla. Serial can be a bear sometimes. The Archive can guide you. Look for RS232 or RS-232 or serial (and so on).

If the Find Instruments button works then that should work.

I got you covered there.

There are probably lots more too.

Eventually you'll want to set up a scan list. You can set it up to trigger itself or you can do it in like an On Cycle loop. It's all very flexible.
