3D Spectrogram State
Activates and deactivates a 3-dimensional spectrogram. As opposed to the common 2-
dimensional spectrogram, the power is not only indicated by a color mapping, but also
in a third dimension, the z-axis.
For details see "Three-Dimensional Spectrograms" on page 592.
Remote command:
CALCulate<n>:SPECtrogram:THReedim[:STATe]
on page 1135
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.
For more details see "Time Frames" on page 590.
Remote command:
CALCulate<n>:SPECtrogram:FRAMe:SELect
on page 1134
History Depth
Sets the number of frames that the R&S FSW stores in its memory.
The maximum number of frames depends on the Sweep Points .
If the memory is full, the R&S FSW deletes the oldest frames stored in the memory and
replaces them with the new data.
Remote command:
CALCulate<n>:SPECtrogram:HDEPth
on page 1134
3-D Display Depth
Defines the number of frames displayed in a 3-dimensional spectrogram.
For details see "Three-Dimensional Spectrograms" on page 592.
Time Stamp
Activates and deactivates the timestamp. The timestamp shows the system time while
the measurement is running. In single sweep mode or if the sweep is stopped, the
timestamp shows the time and date of the end of the sweep.
When active, the timestamp replaces the display of the frame number.
Remote command:
CALCulate<n>:SPECtrogram:TSTamp[:STATe]
on page 1137
CALCulate<n>:SPECtrogram:TSTamp:DATA?
on page 1136
Color Mapping
Opens the "Color Mapping" dialog.
For details see "Color Maps" on page 594.
