I have a Prologix GPIB-USB connected with an Anritsu power meter ML9001a. In the Prologix webpage, it says to communicate with an instrument in Labview,
Send ++addr X
terminated with Line Feed, where X is the GPIB address of the instrument.
I checked tha datasheet of power meter, it didn't mention GPIB address. So how can I know the GPIB address? I conctacted their company and got no reply. Do I need to try from 0 to 30(max value)??
