AD9361 Phase Offset Between RX1 and RX2

I am interested in using the AD9361 to measure the relative phase between inputs on RX1 and RX2. RX1 and RX2 are connected to the fwd and reflected ports of a directional coupler with the goal of using the 9361 as a tuned detector for measuring impedance (need gain and phase). Is there any specification for what the relative phase offset between RX1 and RX2 is? Can I assume this to be somewhat stable over frequency and AGC level due to the LO and base-band clock being the same between RX1 and RX2?
