Let's start with simple steps (basics).
To find out if you can communictae with your instrument, I suggest using MAX (Measurement & Automation Explorer).
It is typically located Start>Programs>National Instruments>Measurement & Automation.
In the configuration browser, click on "Devices and Interfaces". You should see your GPIB card (device). When clicking on "Scan For Instruments", the Power Meter should be listed under it's Address. You can use the "Communicate with Instrument" to see if it responds to simple commands, like *IDN?
This would be the first step. Please note the GPIB address, as you will need it later, to communicate to it within LabView.
