Hello, this means that the function format I choose in the data test is spectrum, but will the average result not be reduced no matter how many times the phase reference is added? Is this the same as the function of Autopower linear? Thank you and look forward to your reply
Phase referencing average relies on a fixed relationship between the reference and response channel. If there is no fixed phase relationship between the two channels, it will average to zero. For example, if one channel is on a car, and the other is on a solid floor, the relationship is broken. In most real world situations (with a mix of random and fixed signal), there is a good chance that the amplitude of a phase referenced spectrum will be lower than the autopower, since and random component is present in the autopower, but averaged out in the spectrum.
