EMC Test Report
Reference No.: NK2EE 267.EMS
6. Immunity to RF voltages (S2a)
6.1 Test criteria and test procedure
Operating environment;
Temperature
20 ℃
Relative Humidity
40 %
The EUT was placed 0.1m above a metallic ground plane of dimensions 2 x 1m.
The wanted signal was fed to all input terminals respectively and the unwanted
signal was fed to mains input, audio output and input terminals respectively.
The criterion concerning acceptable sound interference is a wanted to unwanted
audio signal ratio of ≥40 dB at a wanted signal level of 50 mW.
The audio output power was measured with a 0.5 - 3 kHz band-pass filter.
The audio analyzer was applied without a weighting filter.
The ground connection of the input matching network (Rci), output matching network
(Rco), and mains filter (MSF) were directly connected to the metal table.
The mains filter (MSF) was connected to ground while the other matching networks
are only connected to ground when they are being used as injection ports.
The measurements were performed with test software TS9980 Ver.2.9.
6.2 Measurement uncertainty
Immunity to conducted currents : +/- 2dB
6.3 Test result immunity to conducted voltage.
The equipment does comply with the requirements.
