Trace 1/Trace 2/Trace 3/Trace 4/Trace 5/Trace 6
Selects the active trace (1, 2, 3, 4, 5, 6) and opens the "Trace Mode" submenu for the
selected trace.
The default setting is trace 1 in the overwrite mode (see "Clear Write" on page 253),
the other traces are switched off (see "Blank" on page 254). For details see Chap-
ter 3.2.8.4, "Trace Mode Overview", on page 263.
Tip: To configure several traces in one step, press the Trace Wizard softkey to open a
trace configuration dialog. See also Chapter 3.2.8.2, "Configuring Traces",
on page 260.
Remote command:
Selected via numeric suffix of:TRACe<1...6> commands
Clear Write ← Trace 1/Trace 2/Trace 3/Trace 4/Trace 5/Trace 6
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 ← Trace 1/Trace 2/Trace 3/Trace 4/Trace 5/Trace 6
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 ← Trace 1/Trace 2/Trace 3/Trace 4/Trace 5/Trace 6
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.
