Item Display element Description
14
Selected indicator This inverse-colored line indicates the Spectrogram line that will appear in
the Spectrum display when the Spectrogram trace is enabled. This line is
attached to the selected marker.
15 Clear Clears the spectrogram display; however, data records in acquisition history
remain in memory and are available for replay. To clear memory, select
File >
Acquisition Data Info > Delete All Data .
16 Marker indicators These icons indicate the position of markers in the spectrogram. You can
move markers by dragging the desired marker indicator.
17 Detection setting Displays the selected Detection method (see Settings > Trace (see page 85)
tab).
18 Marker readout Marker readout for the selected marker. In the Spectrogram display, the
marker readout includes a date and timestamp. The time is displayed
in a 24-hour format. The timestamp readout can be shown or hidden
independently of the other marker readouts (see
Settings > Prefs (see
page 106) ).
19 Time Scale status readout Three readouts can appear here depending on settings: Time/update,
Spectrums/line, and Overlap. See
Time Scale Status Readout (see page 84) .

Time Scale Status Readout
Three types of readouts can appear in the display depending on settings:
Time/update – Displays minutes:seconds when Spectrum Monitor is selected in the Settings > Time
& Freq Scale tab in the Vertical (Time) section.
Spectrums/line – Displays an integer number when vertical scale is Normal and each line contains the
results from one or more frequency transforms (whether zoomed out or not).
Overlap – Displays the overlap percentage when vertical scale is Normal and each line’s transform
shares some points with the transforms of lines before and after it (zoomed in). Overlap can only be
done when the Analysis Length > 2x RBW frame length.
The Spectrogram can show results from one or multiple acquisitions and it can show one or multiple
lines for each acquisition.
