Phase Change Timing

I need help making a measurement.

I have a N5181A MXG feeding into a N9020A MXA.  I want to change the phase of the signal and detect how long it takes from, issuing the phase change until it is detected by the MXA.  This will give me the external time, so when I measure group delay in a receiver I can subtract the external time.

I am not even sure I can do this, how to do this, or if I have the right equipment or options.  I am at a loss at this point.
