Abstract
A system for measuring phase coherence between two modulated radio frequency signals comprises at least two measurement receivers coupled with each other and a processing module assigned to the at least two measurement receivers. Each of the at least two measurement receivers is configured to acquire a radio frequency signal and to convert the respective radio frequency signal acquired into digital samples. The processing module is configured to receive the digital samples and to transform the digital samples into a frequency domain to obtain a respective transformed dataset assigned to each measurement receiver. The processing module is also configured to calculate a phase in dependency of the frequency from the respective transformed dataset. Moreover, the processing module is configured to determine a phase difference over frequency based on the transformed datasets. Further, a method of measuring phase coherence between two modulated radio frequency signals is described.
