Making Basic Measurements Using Spectrum Analyzer Mode

Comparing Signals Using Delta Markers

3.Press MARKER A to activate a second marker at the position of the first marker. Move the second marker to another signal peak using the NEXT PK RIGHT or NEXT PK LEFT softkeys or the knob.

4.The amplitude and frequency difference between the markers is displayed in the active function block and in the upper-right corner of the screen. See Figure 4- 12.

Press INIKR), More 1 of 2 , then MARKER ALL OFF to turn the markers

Off.

Figure 4-12. Using the Marker Delta Function

5.The MARKER +PK-PK softkey can be used to find and display the frequency and amplitude difference between the highest- and lowest-amplitude signals. To use this automatic function, press c-1, More I of 2 , MARKER +PK-PK See Figure 4-13.
