8. Radiated Disturbance 
 
8.1 Test Procedure
 
         
        The measurements were performed in the frequency range 30-1000 MHz 
        The disturbance radiation was measured on an open area test site with a reference ground plane and at a 
distance of 3 m. The height of the measuring antenna was varied between 1 to 4 m and the table was rotated 
a full revolution order to obtain maximum values of the electric field intensity.   
The measurement was made in both the vertical and horizontal polarization, and the maximum value is 
presented in the data. Disturbance radiation due to the local oscillator and its fundamental and harmonic 
frequencies was measured on a selected number of broadcast channels.
