The FM envelope delay technique of measuring group delay is an attractive alternative to standard techniques using equipment like the network analyzer. The theoretical basis for this technique is more complicated though leading to some confusion about how to optimize the measurement accuracy. This paper discusses methods of improving accuracy when making group delay measurements using the FM envelope delay technique. The paper concentrates on two effects which are known to limit accuracy in… CONTINUE READING
