Abstract: A method for determining a signal propagation time mismatch in a modulator comprises generating a predetermined signal shape of a amplitude component of a radio frequency signal generating one or more predetermined conditions in a frequency component of the radio frequency signal at a first time interval relative to the predetermined signal shape and detecting the one or more predetermined conditions in the frequency component at a second time interval. The method further includes determining the amplitude component at the second time interval and calculating a signal propagation time mismatch value based on the signal shape of the amplitude component, on the first time interval and the second time interval.

Abstract: A receiver having a test signal generator configured to generate a test signal that free of a requirement to be frequency locked, and to measure a frequency of the test signal; and a local oscillator signal source configured to tune a local oscillator signal to a difference frequency with respect to the measured test signal frequency, wherein the difference frequency falls within a passband of a passband filter of the receiver.
