6. DISTURBANCE RADIATION IN THE FREQUENCY RANGE 30MHz   
TO 1,000MHz
 
 
6.1. Operating environment 
Temperature 
: -6℃ 
Relative humidity  : 38% 
 
    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. 
The test was measured with the main unit and the remote control unit. 
 
6.3. Measurement uncertainty 
 
Radiated disturbance electric field intensity, 30    ~    300 ㎒:  ±2.0 ㏈ 
 
Radiated disturbance electric field intensity, 300 ~ 1,000 ㎒:  ±2.0 ㏈ 
 
The Measurement uncertainty describes the overall uncertainty of the given   
measured value during operation of the EUT in the above-mentioned way.
