Measuring Magnitude and Insertion Phase Response

This measurement example shows you how to measure the maximum amplitude of a surface acoustic wave
(SAW) filter and then how to view the measurement data in the phase format, which provides information
about the phase response.

Measuring the Magnitude Response

1. Connect your test device as shown in
Figure 1-2 Device Connections for Measuring a Magnitude Response
2. Press and choose the measurement settings. For this example the measurement parameters
Preset
are set as follows:
Meas Trans:FWD S21 (B/R)
Center 134
Span 50 M/
3
Power
AUTO SCALE
Scale Ref
Chan 2
Meas Trans:FWD S21 (B/R)
Scale Ref AUTO SCALE
You may also want to select settings for the number of data points, averaging, and IF bandwidth.
3. Remove the device and connect the power cables together (thru) and perform a response calibration
using the following key presses.
Press
Chan 1 Cal
If the channels are coupled (the default condition), this calibration is valid for both channels.
