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.

    7.2. Test set-up and procedure 

Measurements were performed in the frequency range 30 ㎒ to 1,000 ㎒. 

 

The level of the test signal, which was connected to the receiver through a 
combining network, was set to give 70 ㏈㎶  at the input of the EUT. 
The signal was an unmodulated carrier. 
Disturbance voltage due to the local oscillator, it’s fundamental and harmonic 
frequencies was measured with the receiver tuned to a selected number of FM 
sound broadcast channels. Disturbance voltage due to all other sources was 
measured with the receiver tuned to the channel 98.3 ㎒ respectively. 

 
   7.3. Measurement uncertainty 
 

Antenna terminal disturbance voltage, Quasi-peak detection:  ±2.0 ㏈ 

 

The measurement uncertainty describes the overall uncertainty of the given 

 

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