6.1. Operating environment
Temperature
: 14℃
Relative humidity : 35%
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.

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.
