5. MAINS TERMINAL DISTURBANCE VOLTAGE IN THE FREQUENCY
RANGE 0.15MHz TO 30MHz
5.1. Operating environment
Temperature
: 3℃
Relative humidity : 45 %
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.

6. DISTURBANCE RADIATION IN THE FREQUENCY RANGE 30MHz
TO 1,000MHz
6.1. Operating environment
Temperature
: 3℃
Relative humidity : 45%
6.2. Test set-up and procedure
The measurement was performed on an open area test site with a reference
ground plane and at a distance of 3m. The height of the measuring antenna was
varied between 1 to 4m and the table was rotated a full revolution in order to
obtain maximum value of the electric field intensity. The measurement was
made in both the vertical and horizontal polarization, and the maximum value is
presented in the report.
The measurement was performed with a quasi-peak detector.
Disturbance radiation due to the fundamental and harmonic frequencies of the
local oscillator and the other source were measured on a selected number of FM
sound broadcast channels. About the Disturbance radiation value from the other
source, the sixteen maximum values were recorded.
