Uncalibrated measurment of mag and phase of a time domain signal

Hello,

I am interested in recording the raw uncalibrated measurment at a PNA receiver of a time domain signal.  In the example in the attached image, the frequencies of interest would be multiples of 2.5GHz (harmonics of the input data).

Can anyone think of a possible way to provide a phase reference for the receiver?  In a normal S-parameter measurment, the the phase of S21 is relative to the incoming CW wave, but since the incoming wave in this case is an external time domain signal, the PNA would not have its normal reference.

Please see the attached image, and thankyou for any comments.

Regards.
