: 17℃
Relative humidity : 41%
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.

8.2. Test set-up and procedure
The EUT was placed on a non-metallic table of 0.8m height. At the side of the
EUT a non-metallic table of 6m length was placed to provide for movement of
the absorbing clamp. The absorbing clamp was applied successively to all leads
whose length was 25 ㎝ or longer, unscreened or screened. For the read, the
maximum measured value at each frequency which was obtained when the
absorbing clamp is moved along the lead was registered. No metallic object,
including a possible other unit of the EUT or any person, was closer to the lead
or unit than 0.8m. All screened and unscreened cables were measured with an
absorbing clamp, according to EN55013, 5.6.
