DCVG Information

Dear Fellows

i need to know that is there any relationship between PSP and DCVG signal strength, i.e. it is recommanded to conduct dcvg if the signal strength is above 300 mV. and on the other side PSP should not be more negetive than -1.2 V. i am getting only 25 mV signal strength even on -1 V PSP. i need to locate the problem.
