reflection coefficient of PSA

Suppose I want to measure the reflection coefficient, Gamma_L, of my measuring receiver.
I propose to  connect the PSA to my calibrated VNA and perform a standard S-parameter measurement to determine Gamma.
Furthermore, I wish to measure Gamma_L for a whole bunch of different PSA settings and ranges, including configuration with "Range Hold" turned and the range held in Range 3 where the receiver is most sensitive.
My questions are:
(a) is there a better way to measure Gamma_L than this?
(b) how can I do this safely without damaging the PSA mixer or other elements, ie., what is the maximum power the mixer can take (given any possible PSA settings)?
