4.3. Power Line Conducted Emission Limits (Class B)
Frequency Limit (dBV)
(MHz) Quasi-peak Level Average Level
0.15 ~ 0.50 66.0 ~ 56.0 * 56.0 ~ 46.0 *
0.50 ~ 5.00 56.0 46.0
5.00 ~ 30.00 60.0 50.0
NOTE1-The lower limit shall apply at the transition frequencies.
NOTE2-The limit decreases linearly with the logarithm of the frequency in
the range 0.15MHz to 0.50MHz.

4.4. EUT Configuration on Measurement
The following equipments are installed on Conducted Emission Measurement to meet FCC requirements
and operating in a manner which tends to maximize its emission characteristics in a normal application.

EUT : Quiet Tubular Motor
Model Number : DM45F/S-15/32

4.5. Operating Condition of EUT
4.5.1.Turn on the power.
4.5.2.After that, let the EUT work in test mode (Receiving) and measure it.

TRF NO. FCC Part 15 /A Page 9 of 24 Report No.: ES151110012E Ver.1.0

4.6. Test Procedure
The EUT is put on the plane 0.8m high above the ground by insulating support and connected to the AC
mains through Line Impedance Stability Network (L.I.S.N). This provided a 50ohm coupling impedance
for the tested equipments. Both sides of AC line are investigated to find out the maximum conducted
emission according to the FCC regulations during conducted emission measurement.
The bandwidth of the test receiver (R&S ESU) is set at 9KHz in 150KHz~30MHz and 200Hz in
9KHz~150KHz.
The frequency range from 150kHz to 30MHz is investigated

4.7. Measurement Results
PASS.

Please refer to the following pages.

TRF NO. FCC Part 15 /A Page 10 of 24 Report No.: ES151110012E Ver.1.0

5.2. Measuring Standard
FCC Part15, Subpart B, Class B ANSI C63.4-2014

5.3. Radiated Emission Limits (class B)
FREQUENCY DISTANCE FIELD STRENGTHS LIMIT
MHz Meters V/m dB(V)/m
30 ~ 88 3 100 40.0
88 ~ 216 3 150 43.5
216 ~ 960 3 200 46.0
960 ~ 1000 3 500 54.0
Remark：(1) Emission level (dB)V = 20 log Emission level V/m
(2) The smaller limit shall apply at the cross point between two frequency bands.
(3) Distance is the distance in meters between the measuring instrument, antenna and the
closest point of any part of the device or system.

5.4. EUT Configuration on Test
The FCC Class B regulations test method must be used to find the maximum emission during radiated
emission measurement.

5.5. Operating Condition of EUT
5.5.1.Turn on the power.
5.5.2.After that, let the EUT work in test mode (Receiving) and measure it.

5.6. Test Procedure
The EUT is placed on a turn table which is 0.8 meter high above the ground. The turn table can rotate
360 degrees to determine the position of the maximum emission level. The EUT is set 3 meters away
from the receiving antenna which is mounted on an antenna tower. The antenna can be moved up and
down from 1 to 4 meters to find out the maximum emission level. Bilog antenna (calibrated by Dipole
Antenna) and horn antenna are used as a receiving antenna. Both horizontal and vertical polarization of
the antenna are set on test.

The frequency range from 30MHz to 1000MHz was pre-scanned with a peak detector (RBW=100kHz,
VBW=300kHz) and all final readings of measurement from Test Receiver are Quasi-Peak values(Quasi
Peak detector used with a bandwidth of 120 kHz).
The frequency range above 1GHz the measuring instrument use RBW=1 MHz and VBW=3 MHz with
Peak Detector for Peak Values, and use RBW=1 MHz and VBW=10 Hz with Peak Detector for Average
Values.

5.7. Measuring Results
PASS.
