IEEE-488 bus connections
The Model 6517B can be connected to the IEEE-488 bus through a cable equipped with standard
IEEE-488 connectors, an example is shown in the following figure. The connector can be stacked to
allow a number parallel connections to one instrument. Two screws are located on each connector to
ensure that connections remain secure.
Figure 98: Standard IEEE-488 connectors
A typical connecting scheme for a multi-unit test system is shown in the following figure. Although any
number of connectors could theoretically be stacked on one instrument, it is recommended that you
stack no more than three connectors on any one unit to avoid possible mechanical damage.
In order to minimize interference caused by electromagnetic radiation, it is recommended that only
shielded IEEE-488 cables be used. Keithley Instruments Models 7007-1 and 7007-2 shielded IEEE-
488 cables are available from Keithley Instruments.
