GPIB bus operation and reference
Introduction
This section contains information about connecting to and using the GPIB (IEEE-488)
bus. The information is organized as follows:
• GPIB bus standards
• GPIB bus connections
• Selecting the primary address
• QuickBASIC 4.5 programming
• General bus commands
• Front panel GPIB operation
GPIB bus standards
The GPIB bus is the IEEE-488 instrumentation data bus with hardware and programming
standards originally adopted by the IEEE (Institute of Electrical and Electronic Engineers) in
1975. The Model 2000 multimeter conforms to these standards:
• IEEE-488-1987.1
• IEEE-488-1987.2
This standard defines a syntax for sending data to and from instruments, how an instru-
ment interprets this data, what registers should exist to record the state of the instrument,
and a group of common commands.
• SCPI 1991 (Standard Commands for Programmable Instruments)
This standard defines a command language protocol. It goes one step farther than IEEE-
488-1987.2 and defines a standard set of commands to control every programmable aspect
of an instrument.
