To obtain the OBW limits, the routine first calculates the total power of the mea-
sured spectrum (integral over the spectrum). In the next step, the points from the
right edge of the trace are summed up until 2.5% of the total power is reached. The
first vertical marker line is positioned at the corresponding frequency. Then the
application sums up the points from the left edge of the trace until 2.5% of the
power is reached. The second vertical marker line is positioned at this point. 95%
of the power is now between the two vertical marker lines. The distance between
the two frequency markers is the occupied bandwidth which is also displayed
below the diagram in "Statistic" information field.
The description of statistical measurement results is covered in
chapter 5.2.7.9,
"Multi Evaluation Detailed Views: Power, Modulation Quality" , on page 737.
5.2.7.5 Multi Evaluation Detailed Views: Channel Power
These views are only applicable to signals with H-PSK modulation.
The Channel Power (CP) results are displayed in bar graphs of the reverse physical
channels of both the I and Q signal. Separate graphs are available for the I-branch and
the Q-branch of the signal.
Fig. 5-12: CDMA2000 multi evaluation: channel power
The Measurement bar graphs display the power of each channel. The I signal levels
are displayed in the upper bar graph, the Q signal levels are displayed in the lower bar
graph. The bar graphs either show the current, average, or maximum levels as set.
Bars for active channels are colored. Bars for inactive channels are gray.
