EMC Test Report
Reference No.: NK08E 683.EMI
6. Mains Terminal Continuous Disturbance Voltage &
Conducted Disturbance at the telecommunication port
6.1 Test Procedure (EN55013)
The measurements were performed in a shielded enclosure. EUT was connected to an Artificial Mains
Network (AMN). EUT was placed on a wooden table 0.8 m above the grounded floor and at least 0.4 m
from the reference ground plane (wall), EUT was placed at least 0.8m from, and connected via a 1m mains
cable, to the AMN. The output power of the amplifier was set to 1/8 of rated power at 8 ohms load.
The measurements on the terminals for mains connection were conducted between neutral and ground, and
between phase and ground, in the frequency range 150 kHz to 30 MHz.
A peak detector scan was conducted over the defined frequency range on all phases. A comparison of the
results obtained from the different phases was then conducted to find the most emitting phase for each
frequency. This “Worst Case” scan with peak detector is presented detector.

6.2 Test Procedure (EN55022)
The measurements were performed in a shielded enclosure. The telecommunication port of an EUT was
connected to a ISN described in CISPR 22:2005. EUT was placed on a wooden table 0.4 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.
