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

convert the [measured] voltage quantity 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

), as

ins

shown below:

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