9.8.1 Trace Mode
The trace mode determines the way the R&S FPC1000 writes or displays the trace or
which results are displayed.
Note that each time you select another trace mode, the R&S
FPC1000 clears the trace
memory.
The following trace modes are available.
●
"Clear / Write"
Overwrites the displayed measurement results when you start a new sweep.
Selecting the "Clear / Write" mode automatically selects the "Auto Peak" detector .
●
"Max Hold"
Displays the highest levels that have been measured over several sweeps.
Selecting the "Max Hold" trace mode automatically selects the "Max Peak" detec-
tor .
To overwrite a max hold trace, change a parameter in a way that the results cannot
be compared any more, for example the span.
The "Max Hold" trace mode is a good way to detect intermittent signals or the max-
imum values of fluctuating signals, for example.
●
"Min Hold"
Displays the lowest levels that have been measured over several sweeps.
Selecting the "Min Hold" trace mode automatically selects the "Min Peak" detector .
To overwrite a max hold trace, change a parameter in a way that the results cannot
be compared any more, for example the span.
The "Min Hold" trace mode is a good way to highlight signals within noise or sup-
press intermittent signals.
●
"Average"
Displays the average levels that have been measured over several sweeps.
