Characterizing a Filter

To display phase

Complete “To set up a frequency response measurement” or continue from one of the previous marker measurements.

1Display a second trace: Press [Display], [2 grids].

2Activate the second trace and define it as a frequency response measurement:

Press [B], [Measurement Data], [frequency response].

3Specify phase data for the second trace:

Press [Data Format], [phase wrap].

4Couple the markers on traces A and B: Press [Marker], [couple mkrs on].

5Move the markers with the knob to determine phase with respect to frequency response.

6Overlap the two traces:

Press [Shift], [A].

Press [Display] [single grid].

In this example, note that a trace which is displayed is not necessarily active (capable of being configured). You must specifically activate a displayed trace in order to change its configuration. For example, if you have chosen the relative marker in one trace then couple the markers, the marker on the second trace will be absolute, rather than relative, unless you activate the second trace and select the relative marker.

Coupling the markers on two traces lets you compare values at the same frequency
