6 Test results and Measurement Data
6.1 Antenna Requirement
Standard requirement:

47 CFR Part 15C Section 15.203 /247(c)15.203 requirement:
An intentional radiator shall be designed to ensure that no antenna other than that furnished by the
responsible party shall be used with the device. The use of a permanently attached antenna or of anantenna that uses a unique coupling to the intentional radiator, the manufacturer may design the unit
so that a broken antenna can be replaced by the user, but the use of a standard antenna jack orelectrical connector is prohibited.
15.247(b) (4) requirement:
The conducted output power limit specified in paragraph (b) of this section is based on the use ofantennas with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of thissection, if transmitting antennas of directional gain greater than 6 dBi are used, the conducted output
power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1),(b)(2), and (b)(3) of this section, as appropriate, by the amount in dB that the directional gain of theantenna exceeds 6 dBi.
EUT Antenna:

Please see Internal photos

The antenna is Multilayer chip antenna. The best case gain of the antenna is 2.67dBi.

Test Setup:

Test Procedure:

1) The mains terminal disturbance voltage test was conducted in a shieldedroom.
2) The EUT was connected to AC power source through a LISN 1 (Line
Impedance Stabilization Network) which provides a 50Ω/50µH + 5Ω linear
impedance. The power cables of all other units of the EUT wereconnected to a second LISN 2, which was bonded to the ground reference
plane in the same way as the LISN 1 for the unit being measured. A
multiple socket outlet strip was used to connect multiple power cables to asingle LISN provided the rating of the LISN was not exceeded.
3) The tabletop EUT was placed upon a non-metallic table 0.8m above theground reference plane. And for floor-standing arrangement, the EUT wasplaced on the horizontal ground reference plane.
4) The test was performed with a vertical ground reference plane. The rear of
the EUT shall be 0.4 m from the vertical ground reference plane. The
vertical ground reference plane was bonded to the horizontal groundreference plane. The LISN 1 was placed 0.8 m from the boundary of theunit under test and bonded to a ground reference plane for LISNs
mounted on top of the ground reference plane. This distance was between
the closest points of the LISN 1 and the EUT. All other units of the EUT
and associated equipment was at least 0.8 m from the LISN 2.
5) In order to find the maximum emission, the relative positions of equipment
and all of the interface cables must be changed according to
ANSI C63.10: 2013 on conducted measurement.

Test Mode:All modes were tested, only the worst case mode a was recorded in thereport.

Figure 1. Below 30MHz

Figure 2. 30MHz to 1GHz
Test Procedure:

Figure 3. Above 1 GHza. 1) Below 1G: The EUT was placed on the top of a rotating table 0.8
meters above the ground at a 3 meter semi-anechoic camber. The table
was rotated 360 degrees to determine the position of the highest
radiation.
2) Above 1G: The EUT was placed on the top of a rotating table 1.5
meters above the ground at a 3 meter semi-anechoic camber. The table
was rotated 360 degrees to determine the position of the highest
radiation.
Note: For the radiated emission test above 1GHz:
Place the measurement antenna away from each area of the EUT
determined to be a source of emissions at the specified measurement
distance, while keeping the measurement antenna aimed at the sourceof emissions at each frequency of significant emissions, with polarization
oriented for maximum response. The measurement antenna may haveto be higher or lower than the EUT, depending on the radiation pattern ofthe emission and staying aimed at the emission source for receiving the
maximum signal. The final measurement antenna elevation shall be thatwhich maximizes the emissions. The measurement antenna elevation
for maximum emissions shall be restricted to a range of heights of from
1 m to 4 m above the ground or reference ground plane.
b. The EUT was set 3 meters away from the interference-receiving
antenna, which was mounted on the top of a variable-height antenna
tower.
c. The antenna height is varied from one meter to four meters above theground to determine the maximum value of the field strength. Both

horizontal and vertical polarizations of the antenna are set to make themeasurement.
For each suspected emission, the EUT was arranged to its worst caseand then the antenna was tuned to heights from 1 meter to 4 meters (forthe test frequency of below 30MHz, the antenna was tuned to heights 1
meter) and the rotatable table was turned from 0 degrees to 360
degrees to find the maximum reading.
The test-receiver system was set to Peak Detect Function and Specified
Bandwidth with Maximum Hold Mode.
If the emission level of the EUT in peak mode was 10dB lower than thelimit specified, then testing could be stopped and the peak values of the
EUT would be reported. Otherwise the emissions that did not have 10dB
margin would be re-tested one by one using peak, quasi-peak or
average method as specified and then reported in a data sheet.
Test the EUT in the lowest channel (2402MHz),the middle channel(2440MHz),the Highest channel (2480MHz)
The radiation measurements are performed in X, Y, Z axis positioning
for Transmitting mode, and found the X axis positioning which it is theworst case.
Repeat above procedures until all frequencies measured was complete.

Remark:1) The field strength is calculated by adding the Antenna Factor, Cable Factor & Preamplifier. The basic
equation with a sample calculation is as follows:
Final Test Level =Receiver Reading + Antenna Factor + Cable Factor – Preamplifier Factor
2) Scan from 9kHz to 25GHz, the disturbance above 10GHz and below 30MHz was very low. As shown in thissection, for frequencies above 1GHz, the field strength limits are based on average limits. However, thepeak field strength of any emission shall not exceed the maximum permitted average limits specified aboveby more than 20 dB under any condition of modulation. So, only the peak measurements were shown in thereport.
