7.1. Operating environment
Temperature
: 23℃
Relative humidity : 37%
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.
