Understanding Channel Power Measurements

This presentation explains channel power, the sum of all power contained within a defined frequency channel, and the three primary methods used to measure it. Channels, commonly used in wireless communications and broadcast systems, are defined by a center frequency and bandwidth. Get guidance on how to measure channel power using an RF power sensor, a spectrum analyzer in zero span mode, and the integrated bandwidth method. The tutorial emphasizes that all spectrum analyzer channel power measurements require an RMS detector for accurate results and introduces the related concept of adjacent channel leakage ratio (ACLR).

What you’ll learn:

The definition of channel power as the total power within a defined bandwidth, why it matters for wireless communications, and how it relates to adjacent channel leakage ratio (ACLR)How to measure channel power using an RF power sensor, a simple, portable, and accurate method that requires the measured channel to be the only signal present at the sensor inputTwo spectrum analyzer measurement techniques: the zero span metho and the integrated bandwidth method, both requiring an RMS detector for accurate results
