Different biases can result in the opposite phase shifts of the impedance with respect to the applied signal. Neutral gas pressure affects the magnitude of the impedance, but does not change the shape of the frequency response curve. In addition, the position of the grid inside the vacuum chamber has little effect on the impedance.
