3 Test Set-up and Operation Modes
3.1 Principle of Configuration Selection: For emission testing, the EUT was configured to measure its highest possible emission level. Test conditions were adapted according to the instructions for use.
The sequence of testing was:
- Conducted emission tests were performed on 2025-04-03.
- Radiated emission tests were performed on 2025-04-03.
3.2 Equipment and cable arrangement:
Conducted Emission Setup: The setup involves the EUT, LISN (Artificial Mains Network), Transformer, Power Supply, EMI receiver, and Computer. The EUT is placed on a wooden support 0.8m away from the AMN. The power cord is folded to form a bundle of 0.3m to 0.4m length. Disturbance voltage is tested on both neutral and phase lines.
Radiated Emission Setup (30-1000 MHz): The EUT is placed on a 0.8m high wooden table above a reference ground plane within a semi-anechoic chamber. The test distance is 3m. The wooden table is rotated 360°, and the antenna height is varied from 1m to 4m to find maximum disturbance. Tests are performed with both horizontal and vertical antenna polarizations.
Radiated Emission Setup (1-18 GHz): The EUT is placed on an 80cm supporting table within an absorber-lined semi-anechoic chamber. The test distance is 3m. The supporting table is rotated 360°, and the antenna height is varied from 1m to 4m. Tests are performed with both horizontal and vertical antenna polarizations.
3.3 Physical Configuration for Testing: Refer to the related paragraph of this report.
3.4 Test Operation and Test Software: The "Home" APP for iPhone was used during the tests.
3.5 Special Accessories and Auxiliary Equipment:
| No. | Product | Model | Brand |
|---|---|---|---|
| 1 | Mobile phone | iPhone 15 | Apple |
| 2 | Loudspeaker | HomePod mini | Apple |
| 3 | Remote control | E2489 | IKEA |
3.6 Countermeasures to achieve EMC Compliance: No special measure is employed to achieve the requirement.
4 Conformity Decision Rule
For all EMI tests, compliance with limits is determined by comparing measurement results directly with corresponding limits, without taking measurement uncertainties into consideration, provided these uncertainties are less than the values given in CISPR 16-4-2.
