Figure 2-5  Channel Power Measurement Results
NOTE The displayed trace is the current trace, not the averaged trace.
Pressing 
Meas Setup after Channel Power has been selected will access 
the channel power measurement setup menu. Pressing 
Radio Standard 
after 
Mode Setup has been selected will access all the Radio Standards 
available for which this measurement can be applied (NADC MS, 
excluded). Pressing 
Meas Control after Channel Power has been selected 
will access the channel power measurement control menu which allows 
you to pause or restart your measurement, or toggle between 
continuous and single measurement.

MEASURE 
Occupied BW Integrates the power of the displayed spectrum and puts markers at the 
frequencies between which the selected percentage of the power is 
contained. (Refer to Figure 2-4 on page 130.) The measurement defaults 
to 99% of the occupied bandwidth power. The power-bandwidth routine 
first computes the combined power of all signal responses contained in 
the trace. 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 and is the value 
displayed.
The occupied bandwidth function also indicates the difference between 
the analyzer center frequency and the center frequency of the channel. 
This difference is referred to as “Transmit Freq Error” in Figure 2-4 on 
page 130.
