Verification of the generator characteristic as per IEC 61000-4-8
The output current shall be measured with the coil connected. The connection to the antenna shall be made of
drilled cables of max 3 m length and with a sufficient cross-section.
The characteristics to be verified are:
– current value in the standard inductive coils;
– field strength in all other inductive coils;
– total distortion factor in the inductive coils.
For standard inductive coils the verifications shall be carried out with a current probe and measurement
instrumentation having better than <±2 % accuracy.
For all other inductive coils the verification should be carried out with field strength meter, having an <±1dB
accuracy.
