5 One-Button Measurements
Channel Power
Channel Power measures the power and power spectral
density in the specified channel bandwidth. One white frame
on the display indicates the edges of the channel bandwidth.
You need to set the center frequency, reference level, and
channel bandwidth.
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:
Where k is a value between 2 and 6 and n=461 is the
number of trace points.
