Channel Power Measurement
Channel Power measures the Integration Bandwidth, the total power over a fre-
quency range, concentrated on the center frequency of the sweep. It is useful
for channelized (frequency-division multiplexed) signals. Results are shown in
both total power in the channel (in dBm or Watts), and spectral density (dBm or
Watts per Hz).
Setting Channel Power
Note:
For best accuracy, set the center frequency so the signal is
roughly centered before taking measurements. In addition, the span
should be 1½ – 5 times as large as the desired channel width.
1.
Select the Integration Bandwidth (IBW).
Note:
The IBW is automatically set when a channelized frequency
band is selected from the Frequency list.
2.
Type in the desired bandwidth using the keypad.
3.
Press the correct soft key for the desired unit.
Note:
The default unit is MHz.
Note:
The integration bandwidth, channel power, and power density
will be displayed in the “measurement settings” area at the bottom of
the display. Markers 1 and 2 will be turned on, and placed at the band
edges.
