Figure 6-46. Full Two-Port Error Model
6-47 shows the full two-port error model equations for all four S-parameters of a
two-port device. Note that the mathematics for this comprehensive model use all forward and
reverse error terms and measured values. Thus, to perform full error-correction for any one
parameter, all four S-parameters must be measured.
Applications of these error models are provided in the calibration procedures described in
Chapter 5, “Optimizing Measurement Results.
