In the Spectrogram result display all markers are visible that are positioned on a visible
frame.
In the Spectrum Analyzer result display, only the markers positioned on the currently
selected frame are visible. In Continuous Sweep mode this means that only markers
positioned on frame 0 are visible. To view markers that are positioned on a frame other
than frame 0 in the Spectrum Analyzer result display, it is necessary to stop the mea-
surement and select the corresponding frame.

Softkeys of the Spectrogram Menu
The following chapter describes all softkeys available in the "Spectrogram" menu. It is
possible that your instrument configuration does not provide all softkeys. If a softkey is
only available with a special option, model or (measurement) mode, this information is
delivered in the corresponding softkey description.
To display the "Spectrogram" menu, press the [TRACE] key and then select the "Spec-
togram" softkey.

Sets the number of frames that the R&S ESR stores in its memory. The maximum
number of frames depends on the Sweep Points (see "General Information"
on page 402).
If the memory is full, the R&S ESR deletes the oldest frames stored in the memory and
replaces them with the new data.
