Using GPIB
Using GPIB
GPIB enables instruments to be connected together and controlled by a computer. GPIB and its
associated interface operations are defined in the ANSI/IEEE Standard 488.1-1987 and ANSI/IEEE
Standard 488.2-1992. See the IEEE website, http://www.ieee.org, for details on these standards.
The following sections contain information for installing a GPIB interface card or NI-GPIB interface
card for your PC or UNIX-based system.
• “Installing the GPIB Interface Card” on page 62
For more information on setting up a GPIB interface card or NI-GPIB interface card, refer to:
• “Set Up the GPIB Interface” on page 24
• “Verify GPIB Functionality” on page 25
NOTE You can also connect GPIB instruments to a PC USB port using the Agilent 82357A
USB/GPIB Interface Converter, which eliminates the need for a GPIB card. For more
information, go to http://www.agilent.com/find/gpib.
Installing the GPIB Interface Card
Refer to “Installing the GPIB Interface” on page 22.

Before Using the GPIB Examples
HP Basic addresses the signal generator at 719. The GPIB card is addressed at 7 and the signal
generator at 19. The GPIB address designator for other libraries is typically GPIB0 or GPIB1.
