4. MAXIMUM PEAK OUTPUT POWER
4.1. Limits
FCC: For frequency hopping systems operating in the 2400-2483.5 MHz, 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 2400-2483.5 MHz 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 125 mW.
IC: RSS-247§5.4(2)
For FHSs operating in the band 2400-2483.5 MHz, the maximum peak conducted output
power shall not exceed 1.0 W if the hopset uses 75 or more hopping channels; the
maximum peak conducted output power shall not exceed 0.125 W if the hopset uses less
than 75 hopping channels. The e.i.r.p. shall not exceed 4 W, except as provided
insection 5.4(e).
4.2. Test Procedure
a.
b.
For Peak power
The EUT was directly connected to the spectrum analyzer and antenna output port as
show in the block diagram below
Spectrum Setting : RBW > the 20 dB bandwidth of the emission being measured
Span = approximately 5 times the 20 dB bandwidth, centered on a hopping channel
VBW  RBW
Sweep = auto
Detector function = peak
Trace = max hold
For AV power
The Transmitter output (antenna port) was connected to the power meter.
Turn on the EUT and power meter and then record the power value.
Repeat above procedures on all channels needed to be tested.

NOTE: 1.The lower limit shall apply at the transition frequencies.
2.The limit decreases linearly with the logarithm of the frequency in the range
0,15 MHz to 0,50 MHz.
5.1.2. Test Setup
1.The EUT was put on a wooden table which was 0.8 m high above the ground and connected to
the AC mains through the Artificial Mains Network (AMN). Where the mains cable supplied by
the manufacture was longer than 0.8 m, the excess was folded back and forth parallel to the
cable at the center so as to form a bundle no longer than 0.4 m.
2.The EUT was kept 0.4 m from any other earthed conducting surface. Both sides of AC line
were checked to find out the maximum conducted emission levels according to the test
procedure during the conducted emission test.
3.The frequency range from 150 kHz to 30 MHz was investigated.
4.The bandwidth of the test receiver was set at 9 kHz.
5.Pretest for all mode, The test data of the worst case condition(s) was reported on the following

5.2.3. Test Setup
The EUT was placed on a turn table which was 0.8 m above the ground blow 1G and 1.5m above 1G.
The turn table can rotate 360 degrees to determine the position of the maximum emission level. The
EUT was set 3 m away from the receiving antenna which was mounted on an antenna tower. The
measuring antenna moved up and down to find out the maximum emission level. It moved from 1 m to
4 m for both horizontal and vertical polarizations.
The EUT was tested in the Chamber Site. It was pre-scanned with a Peak detector from the spectrum,
and all the final readings from the test receiver were measured with the Quasi-Peak detector.
The bandwidth of the EMI test receiver is set at 120kHz for frequency range from 30MHz to 1000 MHz.
The bandwidth of the Spectrum’s VBW is set at 3MHz and RBW is set at 1MHz for peak emissions
measurement above 1GHz and 1MHz RBW, 10Hz VBW for average emissions measure above 1GHz,
the EUT was placed on a turn table which was 1.5 m above the ground, for all test, used peak
detector.
The frequency range from 30MHz to 10th harmonic (25GHz) are checked. and no any emissions were
found from 18GHz to 25 GHz, So the radiated emissions from 18GHz to 25GHz were not record.
Notes: 1. Emission Level = Antenna Factor + Cable Loss + Meter Reading-Preamp Factor.
2. Measurement Uncertainty: ±3.2 dB at a level of confidence of 95%.
3. For emissions above 1GHz, if peak level comply with average limit, then the average level is
deemed to comply with average limit.
4. For emissions below 1GHz, pretest for all mode, The test data of the worst case condition(s)
was reported on the following pages.
5. EUT Pre-scan X/Y/Z orientation, only worst case is presented in the report (Z orientation).
6. We pretest all modulation, The worst modulation was GFSK, the worst data was show in the
report.

6. 20DB OCCUPY BANDWIDTH
6.1. Limits
According to FCC Section 15.247(a)(1)& RSS-247 §5.1(1)&RSS-Gen§6.6,
the 20dB bandwidth is known as the 99% emission bandwidth, or 20dB
bandwidth(10*log1%=20dB)taking the RF output power
6.2. Test Procedure
1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port
to the spectrum, during the measurement, the Bluetooth module of the EUT is activated and
controlled by the software, and is set to operate under test mode transmitting.
2. Set the spectrum analyzer:
Span: approximately 2 to 3 times the 20dB bandwidth, centered on a hopping channel
RBW ≥1% of the 20dB bandwidth
VBW ≥ RBW
Sweep=auto
Detector function=peak
Trace=max hold
