Vector channel analyzer

A method for measuring characteristics of a signal transmission channel, the method comprising:

• receiving user defined reference parameters at a generator connectable with the signal transmission channel;
• receiving the user defined reference parameters at an analyzer connectable with the signal transmission channel;
• constructing, by the generator, a defined signal as a function of the user defined reference parameters;
• injecting the defined signal into an input of the signal transmission channel;
• receiving an output signal with the analyzer at an output of the signal transmission channel;
• determining a reference delay and/or a reference frequency offset for an output signal at the analyzer without any timing or phase reference connection with the generator;
• computing, by the analyzer, a transfer function of the signal transmission channel, represented as time-dependent and/or frequency-dependent characteristics of the signal transmission channel, calculated with respect to the reference delay and the reference frequency offset;
• and
• displaying or recording results of the computing.
