Auto detector
If the R&S
FPL1000 is set to define the appropriate detector automatically, the detector
is set depending on the selected trace mode:

Analyzing Several Traces - Trace Mode
If several sweep are performed one after the other, or continuous sweep are per-
formed, the trace mode determines how the data for subsequent traces is processed.
After each sweep, the trace mode determines whether:
●
The data is frozen (View)
●
The data is hidden (Blank)
●
The data is replaced by new values (Clear Write)
●
The data is replaced selectively (Max Hold, Min Hold, Average)
Each time the trace mode is changed, the selected trace memory is cleared.
The trace mode also determines the detector type if the detector is set automatically,
see
"Mapping Samples to sweep Points with the Trace Detector"
The R&S
FPL1000 supports the following trace modes:
Table 7-26: Overview of available trace modes
Trace Mode
Description
Blank
Hides the selected trace.
Clear Write
Overwrite mode: the trace is overwritten by each sweep. This is the default setting.
All available detectors can be selected.
Max Hold
The maximum value is determined over several measurements and displayed. The
R&S
FPL1000 saves the sweep result in the trace memory only if the new value is
greater than the previous one.
This mode is especially useful with modulated or pulsed signals. The signal spectrum
is filled up upon each sweep until all signal components are detected in a kind of
envelope.
This mode is not available for statistics measurements.
