PRELIMINARY
Purpose
This appendix provides information on setting up the HP8921 with PCS
interface, the HP8935, the Advantest R3465, and the HP437 and
Gigatronics 8542 power meters. The Cybertest test set doesn’t require
any setup.
HP8921A Test Equipment
Connections
The following diagram depicts the rear panels of the HP 8921A test
equipment as configured to perform automatic tests. All test equipment
is controlled by the LMF via an IEEE–488/GPIB bus. The LMF expects
each piece of test equipment to have a factory-set GPIB address (refer to
Table F-4). If there is a communications problem between the LMF and
any piece of test equipment, you should verify that the GPIB addresses
have been set correctly and that the GPIB cables are firmly connected to
the test equipment.
Figure F-1 shows the connections when not using an external 10 MHz
Rubidium reference.
