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: 2006+A1: 2007. 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.
