Power Bandwidth Average
The Power Bandwidth Average menu defines the power of the internal signal source, sets the step
attenuators and the IF bandwidths, and configures the sweep average.
•
Power defines the power of the internal signal source.
•
Receiver Step Atten... sets the attenuation for all received waves. The generator attenuation is
set automatically.
•
Step Atten. b2.. .sets the attenuation for the received wave b2.
•
RF Off switches the internal power source on (if checked) or off. Switching off the RF power
helps to prevent overheating of a connected DUT while not measurement results are taken.
•
Meas. Bandwidth selects the bandwidth of the IF measurement filter.
•
Average On activates or de-activates the sweep average. With average on the measurement
results are averaged over a selected number of consecutive sweeps (Average Factor).
•
Average Factor defines the number of consecutive sweeps to be averaged.
•
Restart Average starts a new average cycle, clearing all previous results and thus eliminating
their effect on the new cycle. The new cycle is started as fast as possible; an ongoing sweep is
terminated immediately.

Power
Opens the numeric entry bar to set the power of the internal signal source (channel power).
The channel power determines the output power at the test ports if a Frequency Sweep or a Time
Sweep is active; see info below. The setting has no effect in Power Sweep mode, where the source
power is varied over a continuous range .
The selected channel power applies to all source ports used in the active channel. Use the Port
Configuration dialog to modify the output power ranges for the individual analyzer ports.
