Inter–Unit Connection, Testing,
and Control Settings
The following illustrations, tables, and procedures provide the
information necessary to prepare various items of CDMA Test
Equipment supported by the LMF for BTS Calibration and/or
Acceptance Testing.
HP 8921A with PCS Interface
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-8 and Figure F-8). If there is a
communications problem between the LMF and any piece of Test
Equipment, verify that the GPIB Addresses have been set correctly and
that the GPIB Cables are firmly connected to the Test Equipment.
Figure F-13 shows the connections when not using an external 10 MHz
Rubidium Reference.
