7. Conducted Disturbance at the telecommunication port 
 
7.1 Test Procedure 
     
 
The measurements were performed in a shielded enclosure. The telecommunication port of an EUT was   
connected to a ISN described in EN 55022:2010. EUT was placed on a wooden table 0.1 m   
above the grounded floor and at least 0.4 m from the reference ground plane (wall), EUT was placed at least 
0.8 m from ISN. 
        The measurement at telecommunication port was conducted in the frequency range 150 kHz to 30 MHz. 
        A peak detector scan was conducted over the defined frequency range.   
        This “Worst Case” scan with quasi-peak detector & average detector was presented detector.
