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
Preset
measurement parameters are set as follows:

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.
