5. MAINS TERMINAL DISTURBANCE VOLTAGE IN THE FREQUENCY 

RANGE 0.15MHz TO 30MHz

 

 

   5.1. Operating environment 

Temperature 

: 17℃ 

Relative humidity  : 41 % 

 

5.2. Test set-up and procedure 

 

 

 

The mains terminal disturbance voltage was measured with the EUT in a 
Screened room. The EUT was placed on a non-metallic table by 0.8m above   
the metallic grounded floor and 0.4m from the reference ground panel (RGP) 
wall. The distance to other metallic surfaces was at least 0.8m. 
The EUT was tested with the outer conductor of the antenna input connected 
as well as not connected to the ground terminal of the AMN. 
The level of the test signal was 500mV (1 KHz) at coaxial RF input connector. 
Amplitude measurements were performed with a quasi-peak detector and, 
If required, with an average detector. 

 
5.3. Measurement uncertainty 

 

Mains terminal disturbance voltage, quasi-peak detection:  ±2.0dB 

 

Mains terminal disturbance voltage, average detection      :  ±2.0dB 

 

The measurement uncertainty describes the overall uncertainty of the given 

 

measured value during the operation of the EUT in the above-mentioned way.
