The figure 3-4 fully shows the relationship between the Central Frequency and
Reference Fevel. The box in the figure shows a display of the analyzer. Changing of
the Center Frequency changes the location of horizontal line on the display.
Changing the Reference level changes the vertical position of the signal on the
display. If you increase a span, the scope of frequency shown horizontal on the
display will increase.

Please set the marker.
The marker function measures the frequency and amplitude of a signal and places a
diamond-shaped marker on the maximum value of the signal. If you intend to
activate the marker, please press the marker key. The normal button will be
highlighted and the marker value will be displayed in the active function block.
Please place a marker on the maximum value of a signal by turning a scroll knob.
Also, you can automatically place a marker on the peak of trace by using a PEAK
SEARCH key.
The decipherment result of the marker frequency and amplitude will show up on an
activated function block, and on the upper right corner of the display. If you are to
determine the amplitude of a signal, please check the decipherment result of the
marker.
When other function is activated, you can find the marker frequency and amplitude
on the ecipherment result of the marker on the upper right corner of the display.
