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 ESR
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 enve-
lope.
Remote command:
DISP:TRAC:MODE MAXH, see DISPlay[:WINDow<n>]:TRACe<t>:MODE
on page 683
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 ESR saves the smallest of the previously stored/currently measured values in the
trace memory.
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.
Remote command:
DISP:TRAC:MODE MINH, see DISPlay[:WINDow<n>]:TRACe<t>:MODE
on page 683
Average ← Trace 1/Trace 2/Trace 3/Trace 4/Trace 5/Trace 6
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 6.3.1.5, "Detector Overview", on page 399).
This mode is not available for statistics measurements.
Remote command:
DISP:TRAC:MODE AVER, see DISPlay[:WINDow<n>]:TRACe<t>:MODE
on page 683
View ← Trace 1/Trace 2/Trace 3/Trace 4/Trace 5/Trace 6
The current contents of the trace memory are frozen and displayed.
Note: If a trace is frozen, the instrument settings, apart from level range and reference
level (see below), can be changed without impact on the displayed trace. The fact that
the displayed trace no longer matches the current instrument setting is indicated by the
icon on the tab label.
If the level range or reference level is changed, the R&S ESR automatically adapts the
measured data to the changed display range. This allows an amplitude zoom to be
made after the measurement in order to show details of the trace.
Remote command:
DISP:TRAC:MODE VIEW, see DISPlay[:WINDow<n>]:TRACe<t>:MODE
