4.4.1 Power Bandwidth Average Settings
The "Power Bw Avg" menu defines the power of the internal signal source(s), sets the
step attenuators and the IF bandwidths, and configures the sweep average.
4.4.1.1
Power Bw Avg > Power
Defines the power of the internal signal source(s). The settings are identical with the
"Stimulus > Power" settings; see
chapter 4.3.2, "Stimulus > Power"
4.4.1.2
Power Bw Avg > Bandwidth
Sets the measurement bandwidth of the IF filter. The settings apply to all filters in the
active channel. A system error correction (calibration) remains valid when the filter set-
tings are changed.
Optimizing the filter settings
A small filter bandwidth suppresses the noise level around the measurement frequency
and thus increases the dynamic range. On the other hand the time needed to acquire a
single measurement point increases with smaller filter bandwidths. For small bandwidths,
the filter settling time, which is inversely proportional to the bandwidth, is responsible for
the predominant part of the measurement time.
Segmented sweeps
In "Segmented Frequency" sweeps, the filter settings can be selected independently for
each segment. see
chapter 4.4.2.3, "Define Segments (Dialog)"
