This section describes how to determine the measurement values at three frequency points using markers. The Analyzer screen view is shown the screen shot below. In the current example, a reflection standard of SWR = 1.2 is used as a DUT.

Markers

Add marker

Edit stimulus

To create a new marker, use the following softkeys:

Markers > Add Marker

A new marker is placed in the center of the stimulus axis and assigned to be active. To edit just created marker, use the following soft keys:

Markers > Edit Stimulus

Then enter the frequency value in the input field in the graph, e.g. to enter frequency 200 MHz, press «2», «0», «0» and «M» keys on the keypad.

Repeat the above procedure three times to enable three markers at different frequency points.

By default, only active trace markers are displayed on the screen. To enable display markers of two traces simultaneously, activate the marker table.

Marker Table

To open the marker table, use the following softkeys:
