: 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.

Temperature 
: 13℃ 
Relative humidity  : 41% 
 
      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. 
 
   8.3. Measurement uncertainty 
 
Radio interference power:  ±2.0 ㏈ 
 
The Measurement uncertainty describes the overall uncertainty of the given   
measured value during operation of the EUT in the above-mentioned way.
