Measuring Channel Power
Measuring Channel Power
Channel Power measures the power and power spectral
density in the specified channel bandwidth. A white frame
on the display indicates the edge limits of the channel
bandwidth. The user must specify the center frequency,
reference level, and channel bandwidth to be used for the
measurement.
The power calculation method used to determine the channel
power is a traditional method known as the integration
bandwidth (IBW) method. A swept spectrum is used as the
basis for this calculation. Therefore, it is important to set
the resolution bandwidth correctly before making this
measurement using the following formula:
Please refer to the procedures below to set a channal power
measurement.
1 Press
Meas > Channel Power to select the channel power
measurement mode
2 Press Standard Customize to choose the radio stadard.
3 There are four wireless standard options: WCDMA, CDMA,
LTE, GSM. Press WCDMA as an example.
Once the standard is set, the integration bandwidth and
span will be automatically set according to the standard.
