GENERAL DESCRIPTION
1.1
Product Description
The Equipment Under Test (EUT) is a 2.4GHz Transceiver (VR gaming device) designed to be
operated as a controller via BLE (2402-2480MHz with 2MHz channel spacing). The EUT is
powered by 3*1.5V AAA battery. After being paired with the app, the EUT would be able to
interact with the app.
The Model: 95503, 73521, 73522, 73525, 74038, 00887, 50960, 02069, 03060 are the same as
the Model: 63737 in hardware aspect. The difference in model number serves as marketing
strategy. The models are different in color only.
Antenna Type: Internal, Integral
For electronic filing, the brief circuit description is saved with filename: descri.pdf.
1.2
Related Submittal(s) Grants
This is a single application for certification of a transceiver.
1.3
Test Methodology
Radiated emission measurements were performed according to the procedures in ANSI C63.10
(2013). All radiated measurements were performed in an 3m Chamber. Preliminary scans
were performed in the 3m Chamber only to determine worst case modes. All radiated tests
were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in the
“Justification Section” of this Application.
1.4
Test Facility
The 3m Chamber facility used to collect the radiated data is located at Workshop No. 3, G/F.,
World-Wide Industrial Centre, 43-47 Shan Mei Street, Fo Tan, Sha Tin, N.T., Hong Kong. This test
facility and site measurement data have been placed on file with the FCC.

SYSTEM TEST CONFIGURATION
2.1
Justification
The system was configured for testing in a typical fashion (as a customer would normally use it),
and in the confines as outlined in ANSI C63.10 (2013).
The device was powered by new 3 x 1.5V AAA batteries.
For maximizing emissions, the EUT was rotated through 360°, the antenna height was varied from 1
meter to 4 meters above the ground plane, and the antenna polarization was changed. This step
by step procedure for maximizing emissions led to the data reported in Exhibit 3.0.
The unit was operated standalone and placed in the center of the turntable.
The equipment under test (EUT) was configured for testing in a typical fashion (as a customer
would normally use it). The EUT was mounted to a plastic stand if necessary and placed on the
wooden turntable, which enabled the engineer to maximize emissions through its placement in the
three orthogonal axes.
2.2
EUT Exercising Software
There was no special software to exercise the device. Once the unit is powered up, it transmits
the RF signal continuously.
2.3
Special Accessories
There are no special accessories necessary for compliance of this product.
2.4
Measurement Uncertainty
When determining of the test conclusion, the Measurement Uncertainty of test has been
considered.

EMISSION RESULTS
Data is included of the worst case configuration (the configuration which resulted in the highest
emission levels). A sample calculation, configuration photographs and data tables of the emissions
are included.
3.1
Field Strength Calculation
The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the
Amplifier Gain (if any), Average Factor (optional) from the measured reading. The basic equation
with a sample calculation is as follows:
FS = RA + AF + CF - AG - AV
where FS = Field Strength in dBµV/m
RA = Receiver Amplitude (including preamplifier) in dBµV
CF = Cable Attenuation Factor in dB
AF = Antenna Factor in dB
AG = Amplifier Gain in dB
AV = Average Factor in dB
In the following table(s), the reading shown on the data table reflects the preamplifier gain. An
example for the calculations in the following table is as follows:
FS = RR + LF
where
FS = Field Strength in dBµV/m
RR = RA - AG - AV in dBµV
LF = CF + AF in dB
Assume a receiver reading of 52.0 dBµV is obtained. The antenna factor of 7.4 dB and cable
factor of 1.6 dB are added. The amplifier gain of 29 dB and average factor of 5 dB are subtracted,
giving a field strength of 32 dBµV/m. This value in dBµV/m was converted to its corresponding
level in µV/m.
RA = 52.0 dBµV/m
AF = 7.4 dB
CF = 1.6 dB
AG = 29.0 dB
AV = 5.0 dB
FS = RR + LF
FS = 18 + 9 = 27 dBµV/m
RR = 18.0 dBµV
LF = 9.0 dB
Level in µV/m = Common Antilogarithm [(27 dBµV/m)/20] = 22.4 µV/m

MISCELLANEOUS INFORMATION
The miscellaneous information includes details of the test procedure and measured bandwidth /
calculation of factor such as pulse desensitization and averaging factor (calculation and timing
diagram).
8.1
Radiated Emission on the Bandedge
From the following plots, they show that the fundamental emissions are confined in the specified
band (2400MHz to 2483.5MHz). In case of the fundamental emissions are within two standard
bandwidths from the bandedge, the delta measurement technique is used for determining
bandedge compliance. Standard bandwidth is the bandwidth specified by ANSI C63.10 (2013) for
frequency being measured.
Emissions radiated outside of the specified frequency bands, except harmonics, are attenuated by
50dB below the level of the fundamental or to the general radiated emissions limits in
Section 15.209, whichever is the lesser attenuation, which meet the requirement of part 15.249(d).

TEST REPORT
Peak Measurement
Bandedge compliance is determined by applying marker-delta method, i.e. (Bandedge Plot).
Lower bandedge
Peak Resultant field strength = Fundamental emissions (peak value) – delta from the plot
=91.1 dBµV/m – 44.5 dB
=46.6 dBµV/m
Average Resultant field strength = Fundamental emissions (average value) – delta from the plot
=48.7 dBµV/m – 44.5 dB
=4.2 dBµV/m
Upper bandedge
Peak Resultant field strength = Fundamental emissions (peak value) – delta from the plot
=87.1 dBµV/m – 44.4 dB
=42.7 dBµV/m
Average Resultant field strength = Fundamental emissions (average value) – delta from the plot
=44.7 dBµV/m – 44.4 dB
=0.3 dBµV/m
The resultant field strength meets the general radiated emission limit in Section 15.209, which does
not exceed 74 dBµV/m (Peak Limit) and 54 dBµV/m (Average Limit).

Discussion of Pulse Desensitization
Pulse desensitivity is not applicable for this device. The effective period (Teff) is approximately
0.38ms for a digital “1” bit which illustrated on technical specification, with a resolution bandwidth
(3dB) of 1MHz, so the pulse desensitivity factor is 0dB.
8.3
Calculation of Average Factor
The duty cycle is simply the on-time divided by the period:
The duration of one cycle = 100ms
Effective period of the cycle = 2* 0.38= 0.76ms
DC = 0.76 / 100= 0.0076
Therefore, the averaging factor is found by 20log 0.0076= -42.4dB.

Emissions Test Procedures
The following is a description of the test procedure used by Intertek Testing Services Hong Kong
Ltd. in the measurements of transmitter operating under the Part 15, Subpart C rules.
The transmitting equipment under test (EUT) is placed on a wooden turntable which is four feet in
diameter and approximately 0.8m in height above the ground plane for emission measurement at
or below 1GHz and 1.5m in height above the ground plane for emission measurement above 1GHz.
During the radiated emissions test, the turntable is rotated and any cables leaving the EUT are
manipulated to find the configuration resulting in maximum emissions. The EUT is adjusted through
all three orthogonal axis to obtain maximum emission levels. The antenna height and polarization
are also varied during the testing to search for maximum signal levels. The height of the antenna
is varied from one to four meters.
Detector function for radiated emissions is in peak mode. Average readings, when required, are
taken by measuring the duty cycle of the equipment under test and subtracting the corresponding
amount in dB from the measured peak readings. A detailed description for the calculation of the average
factor can be found in Exhibit 8.3.
The frequency range scanned is from the lowest radio frequency signal generated in the device
which is greater than 9 kHz to the tenth harmonic of the highest fundamental frequency or 40 GHz,
whichever is lower.

Emissions Test Procedures (cont’d)
The EUT is warmed up for 15 minutes prior to the test.
AC power to the unit is varied from 85% to 115% nominal and variation in the fundamental
emission field strength is recorded. If battery powered, a new, fully charged battery is used.
Conducted measurements were made as described in ANSI C63.10 (2013).
The IF bandwidth used for measurement of radiated signal strength was 100 kHz or greater when
frequency is below 1000 MHz. Where pulsed transmissions of short enough pulse duration
warrant, a greater bandwidth is selected according to the recommendations of Hewlett Packard
Application Note 150-2. A discussion of whether pulse desensitivity is applicable to this unit is
included in this report (See Exhibit 8.1). Above 1000 MHz, a resolution bandwidth of 3 MHz is
used.
Transmitter measurements are normally conducted at a measurement distance of three
meters. However, to assure low enough noise floor in the forbidden bands and above 1 GHz, signals
are acquired at a distance of one meter or less. All measurements are extrapolated to three meters
using inverse scaling, unless otherwise reported. Measurements taken at a closer distance are so
marked.
