19. A system for measuring characteristics of a signal transmission channel, comprising:
a generator configured to: generate a defined signal as a function of user defined reference parameters; and inject the defined signal into an input of the signal transmission channel;
an analyzer configured to: receive the defined signal from an output of the signal transmission channel, wherein the analyzer includes the user defined reference parameters;
measure a reference delay and a reference frequency offset without any timing or phase reference synchronization with the generator; and compute a time-dependent and/or a frequency-dependent variation of a response of the signal transmission channel relative to the reference delay and the reference frequency offset; and
a display and/or recording device configured to receive results of the analyzer computations.
