EMC Test Report
Reference No.: NK2EE 320.EMS
5. Input immunity to RF voltages (in Differential mode) (S1)
5.1 Test criteria and test procedure
Operating environment;
Temperature
23 ℃
Relative Humidity
40 %
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 EUT was placed 0.1m above a metallic ground plane of dimensions 2 x 1 m.
The measuring set-up was shown in Figure 1 EN55020 (2002).
The principle of operation was similar to the measuring set-up of Figure 1 EN55020 (2002).
The low pass filter was added to prevent influence of the measuring results by
harmonics of the unwanted signal generators.
The lineout of the EUT were applied to an 22k ohm purely resistive road (Ro)
and then to the AF inputs of the test system.
The power supply of the EUT was connected to a standard voltage source
(without special filters).
The measurements were performed with test software TS9980 Ver.2.9.
5.2 Measurement uncertainty
Antenna input immunity +/- 2.0dB
5.3 Test result of input immunity to RF voltages.
The equipment does comply with the requirements.
