Radiated Emission Test
Test Method and test Procedure:
(2)
The EUT was tested according to ANSI C63.10-2013. The radiated test was performed at Timeway EMC
Laboratory. This site is on file with the FCC laboratory division, Registration No. 899988
The EUT, peripherals were put on the turntable which table size is 1m x 1.5 m, table high 0.8 m. All set up
(3)
is according to ANSI C63.10-2013.
The frequency spectrum from 30 MHz to 25GHz was investigated. All readings from 30 MHz to 1 GHz
(4)
(5)
(6)
are quasi-peak values with a resolution bandwidth of 120 kHz. For measurement above 1GHz, peak values
with RBW=VBW=1MHz and PK detector. AV value with RBW=1MHz, VBW=10Hz and PK
detector. Measurements were made at 3 meters.
The antenna high is varied from 1 m to 4 m high to find the maximum emission for each frequency.
Maximizing procedure was performed on the six (6) highest emissions to ensure EUT compliance is with
all installation combinations. All data was recorded in the peak detection mode. Quasi-peak readings was
performed only when an emission was found to be marginal (within -4 dB of specification limit), and are
distinguished with a "QP" in the data table.
The antenna polarization : Vertical polarization and Horizontal polarization.

3. Distance refers to the distance in meters between the measuring instrument antenna and the EUT
4. This is a handhold device. The radiated emissions should be tested under 3-axes position (Lying, Side,
and Stand), After pre-test. It was found that the worse radiated emission was get at the lying position.
5. GFSK was the worse case because it has highest output power

7.0 20dB and 99%Bandwidth Measurement
7.1 Regulation
Intentional radiators operating under the alternative provisions to the general emission limits, as contained in §§
15.217 through 15.257 and in Subpart E of this part, must be designed to ensure that the 20 dB bandwidth of the
emission, or whatever bandwidth may otherwise be specified in the specific rule section under which the
equipment operates, is contained within the frequency band designated in the rule section under which the
equipment is operated.
7.2 Limits of 20dB Bandwidth Measurement
N/A
7.3 Test Procedure.
1. Check the calibration of the measuring instrument (spectrum analyzer) using either an internal calibrator or a
known signal from an external generator.
2. Set the spectrum analyzer as follows: Span =3MHz, RBW =30 kHz, VBW=100 kHz, Sweep = auto Detector
function = peak, Trace = max hold
3. Measure the highest amplitude appearing on spectral display and record the level to calculate results. 6. Repeat
above procedures until all frequencies measured were complete.

8. Maximum Output Power
8.1 Regulation
According to §15.247(b)(1), for frequency hopping systems operating in the 2400-2483.5 MHz band employing at
least 75 non-overlapping hopping channels, and all frequency hopping systems in the 5725-5850 MHz band: 1
watt. For all other frequency hopping systems in the 2400-2483.5MHz band:0.125 watts. According to
§15.247(b)(4), the conducted output power limit specified in paragraph (b) of this section is based on the use of
antennas with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, 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 the antenna exceeds 6 dBi.
8.2 Limits of Maximum Output Power
The Maximum Output Power Measurement is 30dBm.
8.3 Test Procedure
1. Check the calibration of the measuring instrument (spectrum analyzer) using either an internal calibrator or a
known signal from an external generator.
2. Set the spectrum analyzer as follows: Span = approximately 5 times the 20 dB bandwidth, centered on a
hopping channel; RBW > the 20 dB bandwidth of the emission being measured; VBW =
RBW=3MHz; Sweep = 60s; Detector function = PK; Trace = max hold
3. Measure the highest amplitude appearing on spectral display and record the level to calculate results.
4. Repeat above procedures until all frequencies measured were complete.

frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the hopping channel, whichever
is greater, provided the systems operate with an output power no greater than 125 mW.
9.2 Limits of Carrier Frequency Separation
The Maximum Power Spectral Density Measurement is 25kHz or two-thirds of the 20dB bandwidth of the
hopping Channel which is great.
9.3 Test Procedure
1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an
external generator.
2. Set the spectrum analyzer as follows: Span = wide enough to capture the peaks of two adjacent channels:
Resolution (or IF) Bandwidth (RBW) ≥ 1% of the span; Video (or Average) Bandwidth (VBW) ≥ RBW;
Sweep = auto; Detector function = peak; Trace = max hold
3. Measure the separation between the peaks of the adjacent channels using the marker-delta function.
4. Repeat above procedures until all frequencies measured were complete.

1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an
external generator.
2. Set the spectrum analyzer as follows: Span = the frequency band of operation; RBW=100 kHz, VBW=300 kHz;
Sweep = auto; Detector function = peak; Trace = max hold
3. Record the number of hopping channels.
The report refers only to the sample tested and does not apply to the bulk.

11. Time of Occupancy (Dwell Time)
11.1 Regulation
According to §15.247(a)(1)(iii), frequency hopping systems in the 2400-2483.5 MHz band shall use at least 15
channels. The average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of
0.4 seconds multiplied by the number of hopping channels employed. Frequency hopping systems may avoid or
suppress transmissions on a particular hopping frequency provided that a minimum of 15 channels are used.
11.2 Limits of Carrier Frequency Separation
The average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of 0.4
seconds multiplied by the number of hopping channels employed
11.3 Test Procedure
1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an
external generator.
2. Set the spectrum analyzer as follows: Span = zero span, centered on a hopping channel; RBW = 1 MHz; VBW
≥ RBW; Sweep = as necessary to capture the entire dwell time per hopping channel; Detector function = peak;
Trace = max hold
3. Measure the dwell time using the marker-delta function.
4. Repeat above procedures until all frequencies measured were complete.
5. Repeat this test for different modes of operation (e.g., data rate, modulation format, etc.), if applicable.

12 Out of Band Measurement
12.1 Test Setup
The restricted band requirement based on radiated emission test; please see the clause 6 for the test setup
12.2 Limits of Out of Band Emissions Measurement
1. Below –20dB of the highest emission level of operating band (in 100kHz Resolution Bandwidth).
2. Fall in the restricted bands listed in section 15.205. The maximum permitted average field strength is listed in
section 15.209.
12.3 Test Procedure
For signals in the restricted bands above and below the 2.4-2.483GHz allocated band a measurement was made of
radiated emission test. Peak values with RBW=VBW=1MHz and PK detector.
For bandage test, the spectrum set as follows: RBW=100kHz , VBW=300 kHz. A conducted measurement used
Note: 1. For band-edge measurement, the frequency from 30MHz-25GHz was tested. And It met the FCC rule.
2. This is a handhold device. The radiated emissions should be tested under 3-axes position (Lying, Side,
and Stand), After pre-test. It was found that the worse radiated emission was get at the lying position.
The report refers only to the sample tested and does not apply to the bulk.
