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 2016 THD 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 instrument
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.
