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 473.
Remote command:
CALCulate<n>:SPECtrogram:FRAMe:SELect
on page 695
History Depth
Sets the number of frames that the R&S FPL1000 stores in its memory.
The maximum number of frames depends on the Sweep Points .
If the memory is full, the R&S FPL1000 deletes the oldest frames stored in the memory
and replaces them with the new data.
Remote command:
CALCulate<n>:SPECtrogram:HDEPth
on page 695
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.

Color Mapping
Opens the "Color Mapping" dialog.
For details see "Color Maps" on page 475.
Continuous Sweep / Run Cont
After triggering, starts the sweep and repeats it continuously until stopped. This is the
default setting.
While the measurement is running, the "Continuous Sweep" softkey and the RUN
CONT key are highlighted. The running measurement can be aborted by selecting the
highlighted softkey or key again. The results are not deleted until a new measurement
is started.
Note: Sequencer. If the Sequencer is active, the "Continuous Sweep" softkey only
controls the sweep mode for the currently selected channel setup. However, the sweep
mode only takes effect the next time the Sequencer activates that channel setup, and
only for a channel-defined sequence. In this case, a channel setup in continuous
sweep mode is swept repeatedly.
