Evaluating a Duplexer

This section illustrates how to evaluate a duplexer (Tx center frequency: 1.88 GHz, Rx
center frequency: 1.96 GHz).

Evaluation Steps

Here, the DUT is evaluated by following the steps described in Table 15-3.

1. Determine the Segment Sweep Conditions

A segment sweep is performed by following the sweep conditions shown in Table 15-4.
Table 15-4 Sweep Conditions
Chapter 15
Description
Segment sweep conditions are determined according to the
characteristics of the DUT.
The segment sweep conditions are entered in the
E5070B/E5071B.
The segment sweep is selected as the sweep type.
A full 3-port calibration is executed by using the 2-port
ECal module.
The DUT is connected.
The number of traces to be displayed, split display, and
measurement parameters are specified.
A trigger is applied to execute the measurement.
The setup for segment display and for the scale are defined.
The evaluation parameters for the duplexer are determined.
The setup for the limit table is defined.
The limit test is executed.
