Hold
If activated, traces in "Min Hold", "Max Hold" and "Average" mode are not reset after
specific parameter changes have been made.
Normally, the measurement is started again after parameter changes, before the mea-
surement results are analyzed (e.g. using a marker). In all cases that require a new
measurement after parameter changes, the trace is reset automatically to avoid false
results (e.g. with span changes). For applications that require no reset after parameter
changes, the automatic reset can be switched off.
The default setting is off.

Smoothing
If enabled, the trace is smoothed by the specified value (between 1 % and 50 %). The
smoothing value is defined as a percentage of the display width. The larger the
smoothing value, the greater the smoothing effect.
Note: Effects of smoothing on post-processing functions. Note that in Spectrum mode,
all functions performed after the sweep, such as limit checks, markers, or channel
power measurements, are based on the smoothed trace data. Thus, the results will dif-
fer from results based on the original trace.
For more information see
"Trace Smoothing" on page 392.

Average Mode
Defines the mode with which the trace is averaged over several sweeps.
This setting is generally applicable if trace mode "Average" is selected. For FFT
sweeps, the setting also affects the VBW (regardless of whether or not the trace is
averaged).
(See also "Video Bandwidth (VBW)" on page 132).
How many sweeps are averaged is defined by the "Sweep/Average Count"
on page 326.
For details see "How Trace Data is Averaged - the Averaging Mode" on page 391.
"Linear" The power level values are converted into linear units prior to averag-
ing. After the averaging, the data is converted back into its original
unit.
"Logarithmic" For logarithmic scaling, the values are averaged in dBm. For linear
scaling, the behavior is the same as with linear averaging.
