Configurable Test Set (N5230A opt 225)

We have a N5230A PNA-L with option 225 (configurable test set). 

What is the function of Rcvr R1 In signal?  It would appear to be used as a reference against which either the port 1 or port 2 input signal is measured.

Are there any examples available for making use of a substitute signal at this port?

What effect would use of a substitute signal have upon the calibration of the analyzer?
