1. Power cavity impedance is the voltage response exhibited by a hypothetical current source placed at some specific location within the power cavity extents. 2. Low enough so that the additive noise from all sources remains below the allowable noise voltage for each load as attached. 3. It should be made as low as is needed. 4. Ohm's Law.
