2.5 Noise Generating and Noise Suppressing Parts: Refer to the circuit diagram.
2.6 Highest Frequency: The highest frequency used in the EUT is 4 kHz.
2.7 Submitted Documents: Circuit diagram, user's manual, and rating label.
3. Test Set-up and Operation Modes
3.1 Principle of Configuration Selection: The EUT was configured to measure its highest possible emission level. Test conditions were adapted per instructions for use.
3.2 Equipment and Cable Arrangement:
Conducted Emission Setup: The setup includes the EUT, EMI receiver, LISN (Line Impedance Stabilization Network), Transformer, Power Supply, and Computer. The EUT is placed on a wooden support 0.8m from the AMN. Excess cable is bundled to a length of 0.3m to 0.4m.
Radiated Emission Setup: The setup involves the EUT, an antenna, and is conducted in a semi-anechoic chamber. The test distance from the antenna to the EUT is 3m. The EUT is placed on an 80cm wooden support. The antenna height is varied from 1m to 4m, and the support is rotated 360° to find maximum disturbance. Tests are performed with horizontal and vertical antenna polarizations.
3.3 Test Software: No special test software was used.
3.4 Special Accessories and Auxiliary Equipment: An adapter and laptop were used as the power supply.
3.5 Countermeasures to Achieve EMC Compliance: No special measures were employed.
4. Conformity Decision Rule
For all EMI tests, compliance is determined by comparing measurement results directly with limits, without considering measurement uncertainties, as uncertainties are less than specified values (UCISPR in CISPR 16-4-2).
5. Test Results: Emission
5.1 Emission in the Frequency Range up to 30 MHz (Conducted Emission)
The conducted emission tests were performed in a shielded room using quasi-peak and average detectors. The EUT was tested in four operational modes.
Figure 1-8: Spectral Diagrams, Conducted Emission, 150 kHz – 30 MHz. These diagrams show the measured quasi-peak and average emission levels across the frequency range. The upper lines represent the quasi-peak and average limits. The measured emission data points are generally below these limits across all tested modes (L1 and N lines).

5.2 Emission in the Frequency Range above 30 MHz (Radiated Emission)
Radiated emission tests were performed in a semi-anechoic chamber. The test distance was 3m. The EUT was tested in four operational modes.
Figure 9-16: Spectral Diagrams, Radiated Emission, 30 MHz – 1000 MHz. These diagrams display the measured quasi-peak emission levels for horizontal and vertical polarizations across different operational modes. The red line indicates the quasi-peak limit. The measured emissions are generally below the specified limits.
