Ieee-488 Bus Standards; Ieee-488 Bus Connections - Keithley 2002 Getting Started Manual

IEEE-488 bus standards

For remote operation, the Model 2002 uses the IEEE-488 bus for communication between in-
strumentation and the controller (computer). The IEEE-488 bus is also known as the GPIB (Gen-
eral Purpose Interface Bus).
In addition to conforming to the IEEE-488-1978 and IEEE-488.1-1987 standards, the Model
2002 also conforms to the IEEE-488.2-1987 standard and the SCPI 1991 (Standard Commands
for Programmable Instruments) standard. These two standards allow most instrument operations
to be performed with the use of command commands and SCPI commands.

IEEE-488 bus connections

The Model 2002 is connected to the IEEE-488 bus using a cable terminated with standard
IEEE-488 connectors. Figure 15 shows a typical connection scheme for a multi-unit test system.
Note that connectors can be stacked to accomodate the parallel connection scheme.
To minimize interference caused by electromagnetic radiation, only use shielded IEEE-488
cables, such as the Keithley Models 7007-1 and 7007-2.
