EMC Test Report
Reference No.: NK2EE 320.EMS
7. Immunity to RF voltages (in common mode) (S2b)
7.1 Test criteria and test procedure
Operating environment;
Temperature
23 ℃
Relative Humidity
40 %
During the test of immunity to RF voltages (in common mode) the EUT was placed 0.1 M above
a metallic ground plane of dimensions 2 x 1 M.
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 requirements for receivers, multifunction equipment and video tape equipment concerning
the immunity to RF voltages in common mode are restricted to the antenna terminals and
to the frequency range from 26 MHz to 30 MHz.
The cables linking the coupling units to the EUT was short.
A band pass filter was connected to the test system and was used for the EUT AF outputs.
All unused inputs/outputs of the coupling units was terminated with the proper resistance.
The power cable of the EUT was uniformity bundled together and as short as possible.
The measurements were performed with test software TS9980 Ver.2.9.
7.2 Measurement uncertainty
Immunity to conducted currents : +/- 2dB
7.3 Test result immunity to conducted voltage.
The equipment does comply with the requirements.
