How to Characterize the Signal Quality of a Transmission Channel
Measuring phase distortion to optimize transmission channel signal quality
Characterizing the quality of a transmission channel requires optimizing the amplitude flatness and phase distortion to maximize the signal quality at the receiver. A test system that can measure the phase distortion or group delay variation is needed. Phase distortion and group delay as are the most important characteristics that limit the bandwidth of the RF signal path and lead to distortion of the signal in the RF channel.
Optimizing the signal quality in a transmission channel requires a signal analyzer with signal analysis software to perform repeatable channel response measurements such as group delay. You need to measure the phase difference for the adjacent tones, after the signal passes through the device under test (DUT), to determine the group delay.
