GPIB operation
This section contains information about GPIB standards, bus connections, and
primary address selection.
GPIB standards
The GPIB 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 SourceMeter is IEEE-488.1 compliant and
supports IEEE-488.2 common commands and status model topology.
GPIB connections
To connect the SourceMeter to the GPIB bus, use a cable equipped with standard
IEEE-488 connectors as shown in
Figure 11-1.
Figure 11-1
IEEE-488 connector
To allow many parallel connections to one instrument, stack the connectors. Two
screws are located on each connector to ensure that connections remain secure.
Figure 11-2 shows a typical connecting scheme for a multi-unit test system.
To avoid possible mechanical damage, stack no more than three connectors on
any one unit. To minimize interference caused by electromagnetic radiation, use
only shielded IEEE-488 cables. Available shielded cables from Keithley
Instruments are listed in
“Options and accessories” on page 1-5.
