Radiated Immunity - Measurement Standards (5)



High Frequency

1.5m*1.5m area, with 16 field-meter probes, positioned with 0.5m horizontal and vertical spacing.

First Step : For each frequency, the corresponding power level is recorded to obtain the desired field value in the chamber.

This measurement is achieved without the device in the chamber and using several field-meter probes to ensure a good field homogeneity.

Second step : The device under test is disposed in the anechoic chamber and the recorded levels for each frequency are replayed, without the field-meter probe in the chamber.

The step frequency is 1% and the maximum sweep speed is 1.5.10-3 decade per second.

Note all 6 faces of the device under test are to be illuminated.
