Abstract

A measurement system includes an input port, a signal splitter, first and second signal paths, an analysis circuit, and a control circuit. The input port is configured to receive an input signal to be measured. The signal splitter is configured to split the input signal into a first signal that is forwarded to the first signal path and a second signal that is forwarded to the second signal path. The analysis circuit is connected to the first signal path and the second signal path so as to receive both a first processed signal and a second processed signal. The analysis circuit is configured to a complex-valued product signal from the processed signals average the complex-valued product signal over a predetermined number of samples, and determine an averaged power signal based thereon. The control circuit is configured to directly or indirectly add an offset to the averaged power signal.
