Figure 16. Input Conducted EMI Current Test Circuit
An EMCO model 94430-1 current probe was used in this test circuit. The probe has a transfer impedance which is not
constant with frequency. The transfer impedance, expressed in dBS, must be subtracted from the reading as measured on
the spectrum analyzer in dBµV, in order to obtain the true current, measured in dBµA. Note that this is a common-mode
current measurement, where both input lines to the unit under test are measured simultaneously.
