Standard definition is the process of mathematically modeling the electrical characteristics (delay,
attenuation, and impedance) of each calibration standard. These electrical characteristics (coefficients) can
be mathematically derived from the physical dimensions and material of each calibration standard, or from
its actual measured response. The parameters of the standards can be listed in
