4. Test Terminal (When measuring and supplying the voltage, the following terminal is applied.)
Measured common mode impedance may include
measurement error due to stray capacitance, residual
inductance of test fixture.
To correct this error, the common mode impedance should
be calculated as follows;

Measuring Method for Common Mode Impedance
(1) Measure admittance of the fixture (opened), Go Bo.
(2) Measure impedance of the fixture (shorted), Rs Xs.
(3) Measure admittance of the specimen, Gm Bm.
(4) Calculate corrected impedance |Z| using the formula
