Channel Power Measurement
Channel Power measures the Integration Bandwidth, the total power
over a frequency 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. Enter the desired bandwidth.
3. Select 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.
