The voltage between a grid and the cathode of an electron tube.

CONT

By reducing the plate voltage applied to the amplifier, and the screen voltage for a pentode, the amount of negative grid voltage necessary to cut off the flow of plate current is reduced to the value required. Then plate current flows only during the time corresponding to the synchronizing pulses of the composite video signal input, producing separated sync output.
