Other Measurement Examples
Overview
This section illustrates how to use the segment sweep function to evaluate
a SAW bandpass filter with a center frequency of 947.5 MHz.
Procedure
Here, the DUT is evaluated by following the steps.
Step Description
1. Determine the Segment Sweep
Conditions
The segment sweep conditions are
determined according to the
characteristics of the DUT.
2. Create a Segment Sweep Table
The segment sweep conditions are
entered in the E5071C.
3. Select the Segment Sweep as the
Sweep Type
The segment sweep is selected as
the sweep type.
4. Execute the Calibration
A 2-port ECal is performed between
the test ports connecting the DUT.
5. Connect the DUT The DUT is connected.
6. Execute the Measurement
A trigger is applied to perform the
measurement.
7. Define the Setup for Display
The choice is made between
frequency base and order base as the
method of displaying segments.
1. Determine the Segment Sweep Conditions
The following figure shows the results of evaluating the transmission
characteristics of the SAW bandpass filter in the range of 440 MHz to 3
GHz by using the linear sweep.
