A calibration system and method determines magnitudes of traveling-waves at a non-coaxial plane of a scattering parameter measurement device that includes an adapter link between the non-coaxial plane and a coaxial plane. The upper member includes a pressing layer and the base member is associated with a last member. Handle members are disposed at the respective second ends of the elongated arm members. The values of the look-up table are generated by inverting, normalizing, and scaling the uncompensated gain response of the ultra-wideband system. At times during the game, a player will be required to use the fake pistol laying on the game board. The transmission device is connectable both to the housing and to the audio player directly, and is capable of transmitting an audio signal generated by the audio player to a playback device such as a radio.
