State
Activates and deactivates the spectrogram result display
In the Receiver application, the R&S ESW always records spectrogram data. The
"State" function simply controls the spectrogram visibility.
Remote command:
CALCulate<n>:SPECtrogram[:STATe]
on page 534
Select Frame
Selects a specific frame, loads the corresponding trace from the memory, and displays
it in the Spectrum window.
Note that activating a marker or changing the position of the active marker automati-
cally selects the frame that belongs to that marker.
This function is only available in single sweep mode or if the sweep is stopped, and
only if a spectrogram is selected.
The most recent frame is number 0, all previous frames have a negative number.
Remote command:
CALCulate<n>:SPECtrogram:FRAMe:SELect
on page 531
History Depth
Sets the number of frames that the R&S ESW stores in its memory.
The maximum possible size of the spectrogram history depends on the available mem-
ory.
If the memory is full, the R&S ESW deletes the oldest frames stored in the memory
and replaces them with the new data.
Remote command:
CALCulate<n>:SPECtrogram:HDEPth
