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 under adapted test conditions. The sequence of testing was: Conducted emission tests on 2025-02-24 and Radiated emission tests on 2025-02-26.

3.2 Equipment and Cable Arrangement

A block diagram illustrates the conducted emission test setup. It shows the Equipment Under Test (EUT) connected to a Line Impedance Stabilization Network (LISN). The LISN is connected to a transformer, power supply, and then to an EMI receiver and computer for measurement. The EUT is positioned 0.8 meters from the LISN, with the power cord bundled to a length of 0.3-0.4 meters.

A block diagram illustrates the radiated emission test setup. It depicts the EUT placed on a 0.8m high support. A receiving antenna is positioned 3 meters away from the EUT. The antenna height can be varied from 1 to 4 meters, and the EUT is rotated 360 degrees to find maximum disturbance.

3.3 Test Software

No special test software was used.

3.4 Special Accessories and Auxiliary Equipment

During the EMI tests, a dimmer (model: ICDL-20NA-BI-2, brand: IKEA) was used.

3.5 Countermeasures to Achieve EMC Compliance

No other special measures were employed.

Conformity Decision Rule

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