					CISPR 22 (1997) defines the conducted emissions requirements and testing of Information Technology Equipment (ITE). Section C.1.4 of CISPR 22 requires measuring the common mode impedance of an ITE cable bundle with respect to its ground plane, and provides a test method for this measurement. The technique uses one current probe to inductively couple a current into a physically short loop loaded with 50 ohms. The second current probe measures the induced current in the 50 ohm loop. These 2 probes are then used in the same way on the ITE cable bundle to inject and measure a current. CISPR 22 indicates that the ratio of the current in the 50 ohm loop to the current in the loop formed by the ITE cable bundle and the ground plane times 50 ohms yields the common mode impedance of the ITE cable bundle. Section C.1.4 requires the cable bundle to be disconnected from the EUT, and common mode grounded to the reference ground plane for this impedance measurement.
