When the probe is used to measure current, the transfer impedance factors 
convert the 

[measured]

 voltage quantit

y present at the probe’s output port 

into  a  current  quantity  corresponding  to  the  actual  current  through  the 
conductor(s) passing through the probe aperture. 

The transfer impedance factors include the insertion loss of the probe, and 
also perform the function of converting the measured voltage quantity into 
a current quantity.  Based on the assumption that the probe is connected 
to a measuring instrument having a nominal input impedance of 50 ohms, 
this 

conversion is simple Ohm’s Law:

 

 

The  transfer  impedance  factors  are  determined  by  combining  the 
conversion described above with the insertion loss calibration data (

L

ins

), as 

shown below: 

 

The transfer impedance factors can be applied in practice, as follows:
