120 N9320A Spectrum Analyzer
5 One-Button Measurements
Occupied BW
Occupied Bandwidth integrates the power of the displayed
spectrum. The power- bandwidth routine first computes the
power of all signal contained in the trace, then calculates
the span which contains the power of a selected percentage.
The percentage value defaults to 99% of the occupied
bandwidth power.
For 99% occupied power bandwidth, Markers are placed at
the frequencies on either side of 99% of the power. 1% of the
power is evenly distributed outside the markers. The
difference between the marker frequencies is the 99% power
bandwidth.
This is the main menu of occupied bandwidth measurement
including all related parameters and measurement results.

The occupied bandwidth function also indicates the
difference between the analyzer center frequency and the
center frequency of the channel. This “Transmit Freq Error”
