The measurement setup was made according to ANSI C63.4-2014 in a shielded room. The measurement equipment like test receivers, quasi-peak detector and artificial mains network (AMN) are in compliance with CISPR 16-1 series standards.

The tested object was set-up on a wooden support. The EUT was set 0.8 m away from the AMN. The cord longer than necessary to be connected to the AMN was folded forth and back parallel so as to form a bundle with a length between 0.3 m and 0.4 m. The disturbance voltage test was performed on the neutral line and phase line of the power supply of the EUT respectively.

The following figures and tables show the results measured by an automatic measuring system. Both quasi-peak and average measurements were performed. In the spectral diagrams, "Quasi-Peak" and "Average" denote the respective measurement results.

Notes on tables of conducted emission results and conversions:

• Level (dBµV): final measurement results using quasi-peak detector and average detector.
• Transd (dB): transducer factor including cable loss, insertion loss of artificial mains network, and gain of pre-amplifier (if used).
• Margin: Limit (dBµV) - Level (dBµV).

Expanded measurement uncertainty (k=2): 5.40 dB

The minimum margin to the limit is 14.97 dB at 720.155000 MHz. The margin is higher than expanded measurement uncertainty.

The radiated disturbance test was carried out in a semi-anechoic chamber. The test distance from the receiving antenna to the EUT is 3 m. The normalized site attenuation of the semi-anechoic chamber is regularly calibrated to ensure the radiated disturbance test results are valid. During the test, the EUT was placed on a 0.8 m high wooden table above the reference ground plane. The wooden table was rotated 360° around and the height of the antenna was varied from 1 m to 4 m to find the maximum disturbance. The test was performed with the antenna both in its horizontal and vertical polarizations.

The following figures and tables show the results measured by an automatic measurement system. Before final measurement, a survey was made to determine in which state the maximum disturbance was obtained. The final measurement was made in the state the maximum disturbance was obtained. In the spectral diagrams, "Quasi-Peak" denotes the test results.

Notes on tables of radiated emission results and conversions:

• QuasiPeak (dBµV/m): final measurement results using quasi-peak detector.
• Corr. (dB): correction factor including: antenna factor, cable loss, and gain of pre-amplifier (if used).
• Margin: Limit (dBµV/m) - QuasiPeak (dBµV/m).

Note: The class B limits of ICES-005:2018 are stricter than those of FCC 47 CFR Part 15, Subpart B:2023 and ICES-003:2020 for a 3 m test distance. Therefore, the former limits are used in the following figures and tables.

The radiated disturbance test was carried out in an absorber-lined semi-anechoic chamber. The test distance from the receiving antenna to the EUT is 3 m. The site voltage standing wave ratio (SVSWR) of the absorber-lined semi-anechoic chamber is regularly calibrated to ensure the radiated disturbance test results are valid. During the test, the EUT was placed on an 80 cm supporting table. And the supporting table was rotated 360° around, the receiving antenna was kept aiming at the EUT and its height was varied from 1 m to 4 m to find the maximum disturbance. The test was performed with the antenna both in its horizontal and vertical polarizations.

The following figures and tables were measured by an automatic measurement system. The final test was performed with peak detector and average detector at those critical frequencies during the preview test. In the following figure, "Peak" and "Average" denote measurement results with peak detector and average detector.
