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 according to the instructions for use. Tests were performed on 2024-10-28 for both conducted and radiated emissions.

3.2 Equipment and Cable Arrangement

Conducted Emission Setup: The setup included the EUT, a Line Impedance Stabilization Network (LISN), transformer, power supply, EMI receiver, and computer. The EUT was placed on an 80 cm wooden support, 0.8 m away from the AMN.

Radiated Emission Setup: The setup involved the EUT and an antenna. The test was performed at a distance of 3 meters. The antenna height was varied from 1 m to 4 m to find the maximum disturbance. The EUT was placed on an 80 cm wooden support.

3.3 Test Software

No special test software was used during the tests.

3.4 Special Accessories and Auxiliary Equipment

None were used.

3.5 Countermeasures to Achieve EMC Compliance

No other special measures were employed to achieve the requirement.

4. Conformity Decision Rule

For all EMI tests, compliance is determined by comparing measurement results directly with corresponding limits. This is done without considering measurement uncertainties, as the uncertainties are less than the specified values (UCISPR) according to CISPR 16-4-2.

5. Test Results - Emission

5.1 Conducted Emission (0.15 MHz - 30 MHz)

Result: Passed

Test Procedure: FCC 47 CFR Part 15, Subpart B:2023, ICES-005:2018, ANSI C63.4-2014, and CISPR 16-2-1.

Limits: Quasi-peak limits range from 56 to 66 dBμV, and Average limits range from 46 to 56 dBμV across the frequency band (0.15-30 MHz), with values decreasing logarithmically for the initial range.

Test Conditions: Input AC 120 V, 60 Hz; Operational mode: Lighting on; Ambient: Temperature 21.5 °C, Relative humidity 52.3%. Measurement uncertainty was 2.33 dB (k=2).

Setup: Conducted in a shielded room. The EUT was placed on a wooden support 0.8m from the AMN. Disturbance voltage was tested on the neutral and phase lines. The minimum margin to the limit was 5.72 dB.

Spectral Diagrams: Figures 1 and 2 show the conducted emission spectral plots for Line L and Line N, respectively. These plots illustrate measured data against the specified limits. Detailed tables list specific frequency measurements, Quasi-peak and Average values, limits, and margins.

5.2 Radiated Emission (30 MHz - 1000 MHz)

Result: Passed

Test Procedure: FCC 47 CFR Part 15, Subpart B:2023, ICES-005:2018, ANSI C63.4-2014, and CISPR 16-2-3.

Classification: Class B.

Limits: Quasi-peak limits (3m distance) are 40 dBμV/m (30-88 MHz), 43.5 dBμV/m (88-216 MHz), and 46 dBμV/m (216-1000 MHz).

Test Conditions: Input AC 120 V, 60 Hz; Operational mode: Lighting on; Ambient: Temperature 20.5 °C, Relative humidity 45%. Measurement uncertainty was 5.40 dB (k=2).

Setup: Conducted in a semi-anechoic chamber at a 3m test distance. The EUT was placed on an 80 cm wooden support and rotated 360°. Antenna height was varied from 1 m to 4 m. Tests were performed with horizontal and vertical polarizations.

Spectral Diagrams: Figures 3 and 4 show the radiated emission spectral plots for horizontal and vertical polarization, respectively. These plots illustrate measured data against the specified limits. Detailed tables list specific frequency measurements, Quasi-peak values, limits, and margins.
