Scan for GPIB Instruments

To scan for instruments connected to your GPIB interface, complete the following steps:

1. Make sure that your instrument is powered on and connected to your GPIB interface.
2. >  Start Measurement & Automation Explorer.
3. In Measurement & Automation Explorer, expand the Devices and Interfaces directory by clicking on the + next to the folder.
4. Right-click on your GPIB interface and select Scan for Instruments from the drop-down menu that appears.
   Measurement & Automation Explorer displays the connected instruments in the right window pane.

Instruments Not Found

If the Instruments not Found message appears in the right window pane, Measurement & Automation Explorer did not find any instruments. To solve this problem, make sure that your GPIB instruments are powered on and properly connected to the GPIB interface with a GPIB cable. Then, scan for instruments again, as described in the previous section.

Too Many Listeners

If the Too Many Listeners message appears in the right window pane, Measurement & Automation Explorer found too many Listeners on the GPIB. To solve this problem, refer to the following possible solutions:

If you are using an analyzer card on the GPIB, and it is set to participate in the acceptor handshake, your instruments will not be found. Stop capturing with the analyzer and retry the scan for instruments.

If you have a GPIB extender in your system, Measurement & Automation Explorer cannot detect any instruments connected to your GPIB interface. Instead, you can verify communication with your instruments using the Interactive Control utility.

To do so, select Tools»NI-488.2»Interactive Control or click here   to start the Interactive Control utility. For more information about verifying instrument communication, type help "Interactive Control:getting started" at the Interactive Control command prompt.
