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.

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.
