Connect the GPIB cables to your instrument
To connect an instrument to the GPIB interface, use a cable equipped with standard GPIB
connectors, as shown below.
Figure 39: 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.
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 GPIB cables.
Contact Keithley Instruments for shielded cables.
