Below 1GHz:




Above 1GHz:




The radiated emission below 1GHz tests were performed in the 3 meters chamber test site A, above 1GHz
tests were performed in the 3 meters chamber test site B, 1GHz-26.5GHz were performed at the 3 m distance
and 26.5-40 GHz was performed at 1 m distance, using the setup accordance with the ANSI C63.4-2014.
The specification used was with the FCC Part 15 B Class B limits.




                                                                                             Page 7 of 17


 Bay Area Compliance Laboratories Corp. (Dongguan)                         Report No.: RDG190215001-00A

EMI Test Receiver Setup
The system was investigated from 30 MHz to 40 GHz.

During the radiated emission test, the EMI test receiver was set with the following configurations:

              Frequency Range             RBW          Video B/W        IF B/W      Measurement
            30 MHz – 1000 MHz           120 kHz         300 kHz         120 kHz          QP
                                         1 MHz           3 MHz             /            Peak
                Above 1 GHz                             Reduced
                                         1 MHz            video            /            AVG
                                                       bandwidth

If the maximized peak measured value complies with under the QP/Average limit more than 6dB, then it is
unnecessary to perform an QP/Average measurement.

Test Procedure

Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all
installation combinations.

The data was recorded in the Quasi-peak detection mode for below 1 GHz, peak and average detection mode
above 1 GHz.

According to C63.4, the above 1G test result shall be extrapolated to the specified distance using an
extrapolation factor of 20dB/decade from 3m to 1 m
Distance extrapolation factor =20 log (specific distance [3m]/test distance [1m]) dB= 9.54 dB


Corrected Amplitude & Margin Calculation

The basic equation is as follows:

Result = Meter Reading+ Corrected

Note:
Corrected = Antenna Factor + Cable Loss - Amplifier Gain
or
Corrected = Antenna Factor + Cable Loss + Distance extrapolation factor - Amplifier Gain

The “Margin” column of the following data tables indicates the degree of compliance with the applicable
limit. For example, a margin of 7 dB means the emission is 7 dB below the limit. The equation for margin
calculation is as follows:
                                          Margin = Limit – Result
