5. MAINS TERMINAL DISTURBANCE VOLTAGE IN THE FREQUENCY
RANGE 0.15MHz TO 30MHz
5.1. Operating environment
Temperature
: 26℃
Relative humidity : 55 %
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 (1kHz) 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.
