3. Test Set-up and Operation Modes

3.1 Principle of Configuration Selection

Emission: The equipment under test (EUT) was configured to measure its highest possible emission level. The test conditions were adapted accordingly in reference to the instructions for use. Radiated emission tests were performed on 2025-02-25.

3.2 Equipment and cable arrangement

Block diagram for radiated emission test: The setup involves the EUT placed on an 80 cm wooden support above a reference ground plane. The distance from the receiving antenna to the EUT is 3 meters. The antenna height is varied from 1 m to 4 m, and the wooden support is rotated 360 degrees. The test was performed with the antenna in both horizontal and vertical polarizations.

3.3 Test Software

No special test software was used during the tests.

3.4 Special Accessories and Auxiliary Equipment

None.

3.5 Countermeasures to achieve EMC Compliance

No other special measure is employed to achieve the requirement.

4. Conformity Decision Rule

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

5. Test Results Emission

5.1 Emission in the Frequency Range above 30 MHz

5.1.1 Radiated emission

Result: Passed

Date of testing: 2025-02-25

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

Product classification: Class B

Frequency range: 30 – 1000 MHz

Limits (Quasi-peak, 3 m distance):

• 30 – 88 MHz: 40 dBμV/m
• 88 – 216 MHz: 43.5 dBμV/m
• 216 – 1000 MHz: 46 dBμV/m

Bandwidth of EMI receiver for final measurement: 120 kHz

Measurement time for final measurement: 1 s

Kind of test site: Semi-anechoic chamber

Input voltage: DC AA battery 1.2 V dc

Operational mode: Lighting on

Ambient condition: Temperature: 21.8 °C; Relative humidity: 41.2 %

Expanded measurement uncertainty (k=2): 5.40 dB

The minimum margin to the limit is 12.3 dB at 30.970000 MHz. The margin is higher than expanded measurement uncertainty.

The radiated disturbance test was performed in a semi-anechoic chamber. The test distance was 3 m. The normalized site attenuation of the chamber is regularly calibrated. During the test, the EUT was placed on an 80 cm wooden support above the reference ground plane. The wooden support was rotated 360° and the antenna height was varied from 1 m to 4 m to find the maximum disturbance. The test was performed with the antenna in its horizontal and vertical polarizations.

A preview test was performed with a peak detector, followed by a final test with a quasi-peak detector at critical frequencies.
