Reference No.: NK2EE 318.EMI
6. Mains Terminal Continuous Disturbance Voltage
6.1 Test Procedure
The measurements were performed in a shielded enclosure. EUT was connected to an Artificial Mains
Network (AMN). EUT was placed on a wooden table 0.8m above the grounded floor and at least 0.4m 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 8ohms load.
The measurements on the terminals for mains connection were conducted between neutral and ground, and
between phase and ground, in the frequency range 150kHz to 30MHz.
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.
