Characterizing a Duplexer (ES Analyzers Only)

This measurement example demonstrates how to characterize a 3-port device, in this case a duplexer, using
four-parameter display mode. You must use a test adapter or a special 
3-port test adapter to route the signals from the analyzer (a two-port instrument) to the duplexer (a
three-port device). This example procedure is performed using one of the following test adapters:
❏ 8753D Option K36 Duplexer Test Adapter
❏ 8753D Option K39 3-Port Test Adapter
❏ 8753ES Option H39 3-Port Test Adapter (use the same instructions as those for K39 mode)

Definitions

The following abbreviations are used in reference to a duplexer:
Tx Transmitter port
Ant Antenna port
Rx Receiver port

Procedure

1. Press .
Preset
2. Connect the test adapter to the analyzer according to the instructions for your particular model. Connect
any test fixture or cables to the duplexer test adapter. Refer to
Figure 1-40 Duplexer Connections
3. Set up channel 1 for the Tx-Ant stimulus parameters (start/stop frequency, power level, IF bandwidth). In
