Figure 6: GPIB connector
To allow many parallel connections to one instrument, stack the connectors. Each connector has two
screws to ensure that connections remain secure. The figure below shows a typical connection
diagram for a test system with multiple instruments.
Figure 7: IEEE-488 connections
To avoid possible mechanical damage, stack no more than three connectors on any one instrument.
To minimize interference caused by electromagnetic radiation, use only shielded IEEE-488 cables.
Contact Keithley Instruments for shielded cables.
To connect the instrument to the IEEE-488 bus, line up the cable connector with the connector on the
rear panel. Install and tighten the screws securely, making sure not to overtighten them. The following
figure shows the location of the connector.
