4.2 Test Mode
The EUT has been tested under its typical operating condition. Pre-defined engineering
program for regulatory testing used to control the EUT for staying in continuous
transmitting. Only the worst case data were reported.
The EUT has been associated with peripherals pursuant to ANSI C63.10-2013 and
configuration operated in a manner tended to maximize its emission characteristics in a
typical application. Frequency range investigated: radiation (9 KHz to the 10th harmonics
of the highest fundamental frequency or to 40 GHz, whichever is lower).
The EUT has been tested under TX operating condition.
This EUT is a FHSS system, were conducted to determine the final configuration from all
possible combinations. We use software control the EUT, Let EUT hopping on and
transmit with highest power, all the modes GFSK, Π/4-DQPSK, 8DPSK have been tested.
79 Channels are provided by EUT. The 3 channels of lower, medium and higher were
chosen for test.

7.4 Test Procedure
1. The testing follows the guidelines in Spurious Radiated Emissions of ANSI C63.10-2013.
2. Below 1000MHz, The EUT was placed on a turn table which is 0.8m above ground plane. And above
1000MHz, The EUT was placed on a styrofoam table which is 1.5m above ground plane.
3. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a
variable height antenna tower.
4. For each suspected emission, the EUT was arranged to its worst case and then tune the Antenna tower
(From 1m to 4m) and turntable (from 0 degree to 360 degree) to find the maximum reading. A pre-amp
and a high pass filter are used for the test in order to get better signal level to comply with the guidelines.
5. Set to the maximum power setting and enable the EUT transmit continuously.
6. Final measurement (Above 1GHz): The frequency range will be divided into different sub ranges
depending of the frequency range of the used horn antenna. The EMI Receiver set to peak and average
mode and a resolution bandwidth of 1MHz. The measurement will be performed in horizontal and vertical
polarization of the measuring antenna and while rotating the EUT in its vertical axis in the range of 0
degree to 360 degree in order to have the antenna inside the cone of radiation.
7. Test Procedure of measurement (For Above 1GHz):
1) Monitor the frequency range at horizontal polarization and move the antenna over all sides of the EUT(if
necessary move the EUT to another orthogonal axis).
2) Change the antenna polarization and repeat 1) with vertical polarization.
3) Make a hardcopy of the spectrum.
4) Measure the frequency of the detected emissions with a lower span and resolution bandwidth to increase
the accuracy and note the frequency value.
5) Change the analyser mode to Clear/ Write and found the cone of emission.
6) Rotate and move the EUT, so that the measuring distance can be enlarged to 3m and the antenna will be
still inside the cone of emission.
7) Measure the level of the detected frequency with the correct resolution bandwidth, with the antenna
polarization and azimuth and the peak and average detector, which causes the maximum emission.
8) Repeat steps 1) to 7) for the next antenna spot if the EUT is larger than the antenna beamwidth.
7. The radiation measurements are tested under 3-axes(X,Y,Z) position(X denotes lying on the table, Y
denotes side stand and Z denotes vertical stand), After pre-test, It was found that the worse radiation
emission was get at the X position. So the data shown was the X position only.

8.1 REQUIREMENT
According to FCC section 15.247(d), in any 100kHz bandwidth outside the frequency band in
which the spread spectrum or digitally modulated intentional radiator is operating, the radio
frequency power that is produced by the intentional radiator shall be at least 20dB below that in
the 100kHz bandwidth within the band that contains the highest level of the desired power, based
on either an RF conducted or a radiated measurement.

11 Hopping Channel Separation
Test Requirement
FCC CFR47 Part 15 Section 15.247
Test Method
ANSI C63.10:2013
Test Limit
Test Mode
Regulation 15.247(a)(1) Frequency hopping systems shall have
hopping channel carrier frequencies separated by a minimum of 25
kHz or the 20 dB bandwidth of the hopping channel, whichever is
greater. Alternatively, frequency hopping systems operating in the
2400-2483.5MHz band may have hopping channel carrier 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 1W.
Hopping
11.1 Test Procedure
1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port to the
spectrum.
2. Set the spectrum analyzer: RBW = 30KHz. VBW = 100KHz , Span = 3MHz. Sweep = auto; Detector
Function = Peak. Trace = Max hold.
3. Allow the trace to stabilize. Use the marker-delta function to determine the separation between the
peaks of the adjacent channels. The limit is specified in one of the subparagraphs of this Section
Submit this plot.

12.1 Test Procedure
1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port to the
spectrum.
2. Set the spectrum analyzer: RBW = 100KHz. VBW = 300KHz. Sweep = auto; Detector Function = Peak.
Trace = Max hold.
3. Allow the trace to stabilize. It may prove necessary to break the span up to sections. in order to clearly
show all of the hopping frequencies. The limit is specified in one of the subparagraphs of this Section.
4. Set the spectrum analyzer: Start Frequency = 2.4GHz, Stop Frequency = 2.483GHz. Sweep=auto;

ANSI C63.10:2013
Test Limit
Test Mode
Regulation 15.247(a)(1)(iii) Frequency hopping systems in the 24002483.5 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.
The worst case(GFSK) was recorded
13.1 Test Procedure
1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port to the
spectrum.
2. Set spectrum analyzer span = 0. Centred on a hopping channel;
3. Set RBW = 1MHz and VBW = 3MHz.Sweep = as necessary to capture the entire dwell time per hopping
channel. Set the EUT for DH5, DH3 and DH1 packet transmitting.
4. Use the marker-delta function to determine the dwell time. If this value varies with different modes of
operation (e.g.. data rate. modulation format. etc.). repeat this test for each variation. The limit is specified in
one of the subparagraphs of this Section. Submit this plot(s).
