Group Delay measurements with Signal and Spectrum Analyzers
Phase distortions in a transmission channel are determined using group delay measurements, they must be as low as possible to maintain good signal quality. Vector network analyzers are normally used to characterize the group delay variations as a measure of phase distortion.
This application note provides basic information about the concept of a group delay measurement with spectrum analyzers and signal generators, and how this method simplifies the test setup and improves the measurement speed.
