differential interference analysis using HMC 702 and HMC 584

Hello

I am conducting differential interference analysis using HMC 702 and HMC 584, but there is a problem.
The sign of the phase is changed by turning on / off the power supply.
My question is
· Which code of the phase is decided is PLL IC or VCO?
· Is it possible to control the sign of the initial phase and phase (Θ or - θ) when the PLL is locked?
· If possible, is it possible by register manipulation or does it require external circuitry?
is.
Waiting for your answer.

Best regerds.
