how to know the GPIB address of instrument?

[cantata2014]

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)??:womansad:

The actual allowed range should be 1 to 32.  0 is the controller.

Every instrument I have seen has some way of setting the GPIB address, either with switches in the back or through a menu.  Most instruments usually flash the GPIB address on start up.  So you might be able to just turn off the supply and turn it back on and it will show you the address.

Hi,

I checked the power meter again and it didn't flash GPIB address when starting up. But there is a switch at the back, is this the GPIB address? If it is, I guess the GPIB address is 15? and I can set GPIB by changing switch?

Yes, it's 15. As the manual probably says, turn off the instrument before changing the address.

Connect your instrument with a computer with lab view installed .. Open the "Measurement and Automation Explorer" and then go to "Device and interface" .. Click on "GPIB" (should be the first open in the menu .. On clicking the GPIB on the right side a new window will open .. In that window on the top toolbar there will be an option "Scan for instruments" .. Click on it .. As soon as the scan is complete a small window will appear at the bottom which will list your device and the address of ur device ..
