This parameter is only available for Configure measurement settings > "Fre-
quency"/"Power".
"Fast"
Fast measurement with an integration time of 2 ms for each measure-
ment step.
"Normal"
A longer but more precise measurement (integration time is 20 ms/
step).
Remote command:
:SENSe[:POWer]:SWEep:FREQuency:TIMing[:MODE] on page 514

Average - Power Analysis
Selects the averaging factor in time domain.
The factor determines how many measurement cycles are used to form a measure-
ment result. Higher averaging counts reduce noise but increase the measurement
time. Averaging requires a stable trigger event so that the measurement cycles have
the same timing. If factor 1 is selected, no averaging is performed.
This parameter is only available for Configure measurement settings > "Time".

Spacing - Power Analysis
Sets the mode for calculating the sweep steps.
In power versus frequency mode, selection between linear and logarithmic spacing is
possible.
"Linear"
●
Power versus frequency
In a linear sweep, the frequency is swept in equidistant steps over
the continuous frequency range. The x-axis is a linear frequency
axis.
●
Power versus power
The sweeps are performed at constant frequency but with vari-
able generator power that is swept in linear, equidistant steps
over a continuous range. The x-axis is a dB-linear power axis.
●
Power versus time
The sweeps are performed at constant frequency and stimulus
power. The measurement is repeated over a specified period of
time at constant time intervals.
"Logarithmic"
Power versus frequency
In a logarithmic sweep, the frequency is swept in equidistant steps on
a logarithmic scale. The x-axis is a logarithmic frequency axis.

Execution - Power Analysis
Selects single or continuous mode in power analysis.
