Appendix Compensation
3. Electrical Length Compensation
In a single-port (Two-Terminal) impedance measurement at higher frequencies (RF region or higher), the wavelengths of
the electrical signal are so short that the length of the signal transmission line including the test fixture and cables can
cause an undesirable phase shift error. The phase shift error is corrected by the electrical length compensation, which
should be performed in combination with the open/short compensation.
The following measurement instruments are equipped with electrical length compensation function.
