Use the following procedure to manually test an 8960 that is running an
E1960A GSM Test Application. A test record is included to assist in
collecting test data. Make a copy of the test record to use.
The test equipment required for 8960 Operational Verification is:
ESG E4433B Digital Signal Generator
VSA E4406A Transmitter Tester
8960
RF In/Out
To perform the 8960 Operational Verification tests requires that the 10 MHz
timebases be connected together. Connect the 10 MHz Reference Output of the 8960
to the 10 MHz Ref In of the ESG E4433B. Connect the 10 MHz Ref Out of the ESG
E4433B to the 10 MHz Ref In of the VSA E4406A with BNC cables.
The RF In/Out Connector of the 8960 will be alternately connected to either the RF
Out of the ESG E4433B (RX Test) or the RF Input of the VSA E4406A (TX Test) with
a low loss Type-N cable.
