8. Radiated Disturbance
8.1 Test Procedure
The EUT was placed on a wooden table 0.8 m above the ground plane, at the edge of the turntable.
Cables connected to EUT were fixed to cause maximum emission.
A maximum emitting point for each frequency was found by turning EUT 0-360 degrees, adjust between
the antenna height 1 to 4 m for below 1 GHz and fix the antenna height 1.3 m for above 1 GHz.
These measurements were done at a semi anechoic screened enclosure at 10 m distance with a quasi-peak
detector for 30 MHz - 1 GHz and at 3 m distance with a peak & average detector for 1 GHz - 2 GHz.
