3.2.8.4 Trace Mode Overview
The traces can be activated individually for a measurement or frozen after completion
of a measurement. Traces that are not activate are hidden. Each time the trace mode
is changed, the selected trace memory is cleared.
The R&S FSVA/FSV offers 6 different trace modes:
Clear Write
Overwrite mode: the trace is overwritten by each sweep. This is the default setting.
All available detectors can be selected.
Remote command:
DISP:TRAC:MODE WRIT, see DISPlay[:WINDow<n>]:TRACe<t>:MODE
on page 747
Max Hold
The maximum value is determined over several sweeps and displayed. The
R&S FSVA/FSV saves the sweep result in the trace memory only if the new value is
greater than the previous one.
The detector is automatically set to "Positive Peak".
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 enve-
lope.
This mode is not available for statistics measurements.
Remote command:
DISP:TRAC:MODE MAXH, see DISPlay[:WINDow<n>]:TRACe<t>:MODE
on page 747
Min Hold
The minimum value is determined from several measurements and displayed. The
R&S FSVA/FSV saves the smallest of the previously stored/currently measured values
in the trace memory.
The detector is automatically set to "Negative Peak".
This mode is useful e.g. for making an unmodulated carrier in a composite signal visi-
ble. Noise, interference signals or modulated signals are suppressed whereas a CW
signal is recognized by its constant level.
This mode is not available for statistics measurements.
Remote command:
DISP:TRAC:MODE MINH, see DISPlay[:WINDow<n>]:TRACe<t>:MODE
on page 747
Average
The average is formed over several sweeps. The Sweep Count determines the number
of averaging procedures.
All available detectors can be selected. If the detector is automatically selected, the
sample detector is used (see Chapter 3.2.8.6, "Detector Overview", on page 265).
