MARKER A

Spectrum Analyzer Mode Key Descriptions

Spectrum Analyzer Mode Functions

activates a second marker at the position of the first marker.

(If no marker is present, two markers appear at the center

of the display.) The amplitude and frequency of the first

marker is fixed, and the second marker is under your

control. Annotation in the active function block and in the

upper-right corner of the screen indicates the frequency and

amplitude differences between the two markers. The display

mode must not be changed between log and linear while

using a delta marker.

NOTE

If there are already four markers when MARKER A is pressed, a nonactive marker disappears, the

active marker becomes a reference marker, and the delta marker becomes the active marker.
