Spectrum Analyzer Mode Key Descriptions

Spectrum Analyzer Mode Functions

MARKER A

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.

N O T E

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.
