3 Test Set-up and Operation Modes

3.1 Principle of Configuration Selection

For emission testing, the EUT was configured to achieve its highest possible emission level. Test conditions were adapted based on the instructions for use. Radiated emission tests were performed on 2024-12-31, and conducted emission tests were performed on 2025-01-02.

3.2 Equipment and Cable Arrangement

Block diagrams illustrating the test setups for conducted and radiated emission tests are provided. The conducted emission setup involves the EUT, EMI receiver, LISN, transformer, power supply, and computer. The radiated emission setup includes the EUT, antenna, EMI receiver, and computer, with the EUT placed on a wooden support at a specified distance from the antenna.

3.3 Test Software

No special test software was utilized during the tests.

3.4 Special Accessories and Auxiliary Equipment

None were used.

3.5 Countermeasures to achieve EMC Compliance

No specific measures were employed to achieve compliance beyond standard setup procedures.

4 Conformity Decision Rule

For all EMI tests in this report, compliance is determined by comparing measurement results directly with the specified limits. Measurement uncertainties are considered less than the values given in CISPR 16-4-2, and therefore, they are not factored into the compliance determination.
