Model 6517A Getting Started Manual Remote Operation 3-3
IEEE-488 bus standards
For remote operation, the Model 6517A can use the IEEE-488 bus for communication
between instrumentation and the controller (computer). The IEEE-488 bus is also known
as the GPIB (General Purpose Interface Bus).
In addition to conforming to the IEEE-488-1978 and IEEE-488.1-1987 standards, the
Model 6517A also conforms to the IEEE-488.2-1987 standard and the SCPI 1994
(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.
RS-232 standard
For remote operation, the Model 6517A can use the RS-232 serial port for communication
between instrumentation and the controller (computer). All commands, except DDCs, can
be used over this serial port. The serial port is based on the electrical and mechanical char-
acteristics of the RS-232-C standard.
IEEE-488 bus connections
The Model 6517A is connected to the IEEE-488 bus using a cable terminated with stan-
dard IEEE-488 connectors. Figure 3-1 shows a typical connection scheme for a multi-unit
test system. Note that connectors can be stacked to accommodate 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.
