5 Remote GPIB Interface
The N4962A can be controlled and queried with the rear-panel GPIB interface.
The GPIB interface complies with IEEE standard 488.2-1992. To learn more
about the GPIB interface, consult the following books from the IEEE:
• The International Institute of Electrical and Electronic Engineers. IEEE
Standard 488.1-1987, IEEE Standard Digital Interface for Programmable
Instrumentation. New York, NY, 1987.
• .The International Institute of Electrical and Electronic Engineers. IEEE
Standard 488.2-1987, IEEE Stand Codes, Formats, Protocols and
Communication Commands for Use with ANSI/IEEE Std 488.1-1987.
New York, NY, 1987.
A GPIB interface requires that all devices on a common bus have different
addresses; the 5-bit address control switch is located on the back panel next to
the GPIB connector. The factory default address is 25. The address uses a
three digit format. The first digit is always set to “7”, and the last two digits are
programmed by the 5 bit control switch located on the back of the instrument.
The N4980A multi-instrument BERT software is available from Agilent
Technologies for fast GPIB programming of the N4962A.
