Purpose
This appendix provides information on setting up the HP8921 with PCS
interface, the HP8935 and the Advantest R3465. The Cybertest test set
doesn’t require any setup.
HP8921A Test Equipment
Connections
Table F-1 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.
