15. Measurement Examples
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 15-3 Evaluating the DUT Using the Segment Sweep
Step Description
“1. Determine the Segment Sweep
Conditions” on page 497
Segment sweep conditions are determined according to the
characteristics of the DUT.
“2. Create a Segment Sweep Table” on
page 498
The segment sweep conditions are entered in the
E5070B/E5071B.
“3. Select the Segment Sweep as the Sweep
Type” on page 499
The segment sweep is selected as the sweep type.
“4. Execute the Calibration” on page 499 A full 3-port calibration is executed by using the 2-port
ECal module.
“5. Connect the DUT” on page 501 The DUT is connected.
“6. Define the Setup for Display” on page 502 The number of traces to be displayed, split display, and
measurement parameters are specified.
“7. Execute the Measurement” on page 502 A trigger is applied to execute the measurement.
“8. Define the Setup for the Segment Display
and Scale” on page 502
The setup for segment display and for the scale are defined.
“9. Analyze the Parameters” on page 503 The evaluation parameters for the duplexer are determined.
“10. Define the Setup for a Limit Table” on
page 505
The setup for the limit table is defined.
“11. Execute the Limit Test” on page 506 The limit test is executed.
