摘要
A method of determining a total delay to a radio frequency (RF) signal caused by a path between a start point and an end point comprising, injecting a plurality of frequency tones at the start point, wherein the frequency tones are of different frequency, receiving the plurality of frequency tones at the end point, measuring a plurality phase differences corresponding to difference of phase between the plurality of frequency tones injected at the start point and the corresponding plurality of the frequency tones received at the end point, and determining a total delay to the RF signal caused by the path from at least more than one of the plurality of phase differences measured. The method further comprises determining a total phase shift to the RF signal from the total delay and a frequency of the RF signal.
