Using GPIB
Chapter 18
4. Verifying GPIB Functionality
Use the VISA Assistant, available with the Agilent IO Library or the Getting Started Wizard
available with the National Instrument IO Library, to verify GPIB functionality. These utility
programs allow you to communicate with the signal generator and verify its operation over
the GPIB. Refer to the Help menu available in each utility for information and instructions on
running these programs.
If You Have Problems
1. Verify the signal generator’s address matches that declared in the program (example
programs in Chapter 2 use address 19).
2. Remove all other instruments connected to the GPIB and re-run the program.
3. Verify that the GPIB card’s name or id number matches the GPIB name or id number
configured for your PC.
GPIB Interface Terms
An instrument that is part of a GPIB network is categorized as a listener, talker, or controller,
depending on its current function in the network.
listener A listener is a device capable of receiving data or commands from other
instruments. Several instruments in the GPIB network can be listeners
simultaneously.
talker A talker is a device capable of transmitting data. To avoid confusion, a GPIB
system allows only one device at a time to be an active talker.
controller A controller, typically a computer, can specify the talker and listeners
(including itself) for an information transfer. Only one device at a time can
be an active controller.
