The test setup was made according to EN 61000-6-3:2007+A1 in a semi-anechoic chamber. The test distance from the receiving antenna to the EUT is 3m. The normalized site attenuation of the semi-anechoic chamber is regularly calibrated to ensure the radiated disturbance test results are valid. During the test, the EUT was placed on the turntable. The turntable can be rotated 360o around and the receiving antenna was varied from 1m to 4m to find the maximum disturbance. The test was performed with the antenna both in horizontal and vertical polarizations. The following figures were those measured and recorded by a test receiver. The curves in the figure were those measured with a peak detector. The symbol “ +” in the figures are those of quasi-peak value which were measured in final measurement. Quasi-peak detector measurement was only performed at those critical frequencies obtained during the test with peak detector.

The particular performance criterion for the immunity tests are as listed in clause 4 of EN 61000-6-2:2005 is listed as follows: Performance criterion A: The apparatus shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the apparatus is used as intended. The performance level may be replaced by a permissible loss of performance. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of those may be derived from the product description and documentation, and from what the user may reasonably expect from apparatus if used as intended. Performance criterion B: The apparatus shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the apparatus is used as intended. The performance level may be replaced by a permissible loss of performance. During the test, degradation of performance is however allowed. No change of actual operating state or stored data is allowed. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of those may be derived from the product description and documentation and what the user may reasonably expect from the apparatus if used as intended. Performance criterion C: Temporary loss of function is allowed, provided the function is self-recoverable or can be restored by the operation of the controls.

Grid connected inverter frequently use Hall effect current sensors. However, these sensors are designed to operate in locations where high levels of magnetic fields exist (close vicinity of power conductors). Those amplitudes are much higher than the levels of the test according to IEC 61000-4-8. It can therefore be considered that the disturbance applied by the test is negligible compared to the operating environment of this sensitive component. Therefore, the sample is deemed to meet the requirements of IEC 61000-4-8 without actual testing.
