Playback Ref Line Controls the placement of the pink line across the
screen. The playback ref line is displayed 1 pixel
under the trace identified by a Playback Trace
Number. Said another way, the spectrogram trace
identified by Playback Trace Number is drawn 1 pixel
above the playback reference line.
Playback Ref Line is
only available for
spectrogram lines, but
not for Waterfall,
because there is no spectrogram line.
Playback Trace
Date/Time
This softkey launches a time/date entry dialog box.
With the time/date collected from that dialog, the
recorded trace with the time nearest (exact, or
previous to the entered time) is set to the Playback
Trace Number. This allows the user to jump to an
approximate time in the recording, rather than
navigating by index. See also, “Playback Trace
Date/Time Dialog Box” on page 549.
