Measuring Magnitude and Insertion Phase Response

The analyzer allows you to make two different measurements simultaneously. You can make these measurements in different formats for the same parameter. For example, you could measure both the magnitude and phase of transmission. You could also measure two different parameters (Sll and S&.

This measurement example shows you how to measure the maximum amplitude of a 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 2-29.

2.Press 1presei) and choose the measurement settings. For this example the measurement parameters are set as follows:

You may also want to select settings for the number of data points, averaging, and IF bandwidth.

3. Substitute a thru for the device and perform a response calibration for both channel 1 and channel 2.
