Intertek's process follows the requirements of IEC 61000-4-6, the basic standard, with resulting data collection providing very granular resolution.

While this procedure may produce many data points, we will reduce the coupling factor data to a manageable value while maintaining an accuracy of 0.1 dB with respect to the full breath of data. Impedance data will be plotted and compared to requirements listed in IEC 61000-4-6.

The table shown below describes our scope of accreditation for coupling decoupling network calibrations:

Parameter/EquipmentRangeBest Uncertainty (±)Comments
CDN (50 to 150) ΩIEC 61000-4-6
Coupling Factor150 kHz to 230 MHz0.49 dB
Impedance150 kHz to 230 MHz0.38 Ohms
