Radiated Emission Test Results (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.
Product Classification: Class B.
Frequency Range: 30 – 1000 MHz.
Limits (3 m distance): 30-88 MHz (40 dBuV/m), 88-216 MHz (43.5 dBuV/m), 216-1000 MHz (46 dBuV/m).
Bandwidth of EMI receiver: 120 kHz.
Measurement time: 1 s.
Test site: Semi-anechoic chamber.
Supply voltage: AC 120 V, 60 Hz.
Operational mode: Lighting on.
Ambient condition: Temperature: 20.6 °C; Relative humidity: 51.8%.
Expanded measurement uncertainty (k=2): 5.40 dB.
Minimum margin: 8.7 dB at 732.420000 MHz.
Test setup: Carried out in a semi-anechoic chamber, 3 m test distance. EUT on 0.8 m high wooden table. Table rotated 360°, antenna height varied 1-4 m. Tests performed in horizontal and vertical polarizations.
Note 1: The highest frequency in the EUT is less than 108 MHz. According to FCC Part 15 subpart B §15.33 (b) (1), the upper frequency for radiated emission measurement is 1000 MHz.
Note 2: The class B limits of ICES-005:2018 are stricter than those FCC 47 CFR Part 15, Subpart B:2023 for 3m distance, so ICES-005 limits are used.
