Section 2: General operation
Install the GPIB cards in your computer
Refer the manufacturer's documentation for information on installing the GPIB cards.
Connect the GPIB cable
To connect a Model 707B or 708B to the GPIB bus, use a cable equipped with standard IEEE-488
connectors, as shown below.
To allow many parallel connections to one instrument, stack the connectors. Two screws are located
on each connector to ensure that connections remain secure. The figure below shows a typical
connection 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.
Contact Keithley Instruments for shielded cables.
