Understanding Channel Power Measurements
Author: Paul Denisowski, Test & measurement expert
The following will provide an introduction to what channel power is and the three most common ways that channel power is measured.
In order to understand channel power, channel needs to be defined. When signals are transmitted by wireless communication and broadcast systems, they are often assigned specific frequency ranges or channels. Most of the signal power should stay within this channel.
A channel can be defined by a start and stop frequency, but more commonly we define a channel in terms of its width and center frequency.
