Note 3: Only radio communication receivers operating in stand-alone mode within the band 30-960 MHz,
as well as scanner receivers, are subject to Industry Canada requirements, so this test is not applicable.

4.5 Measurement Results Explanation Example
4.5.1
For conducted test items:
The offset level is set in the spectrum analyzer to compensate the RF cable loss and attenuator between EUT
conducted output port and spectrum analyzer. With the offset compensation, the spectrum analyzer reading level
is exactly the EUT RF output level.
The spectrum analyzer offset is derived from RF cable loss and attenuator factor.
Offset = RF cable loss + attenuator factor.
4.5.2
For radiated band edges and spurious emission test:
Per part 15.35(c), the EUT Bluetooth average emission level could be determined by the peak emission
level applying duty cycle correction factor, to represent averaging over the whole pulse train.
The average level is derived from the peak level corrected with “Duty cycle correction factor”.
Average Emission Level (dBuV/m) = Peak Emission Level (dBuV/m) + Duty cycle correction factor (dB)
Duty cycle correction factor (dB) = 20 * log (Duty cycle).
Duty cycle = on time / 100 milliseconds
On time = dwell time * hopping number in 100 ms
For example: bluetooth with dwell time 2.9 ms and 3 hops in 100 ms, then
Duty cycle correction factor (dB) = 20 * log ((2.9 * 3) / 100) = -21.21 dB
Following shows an average computation example with duty cycle correction factor = -21.21 dB, and the peak
emission level is 45.61 dBuV/m.
Example:
Average Emission Level (dBuV/m) = Peak Emission Level (dBuV/m) + duty cycle correction factor (dB)
= 45.61 + (-21.21) = 24.4 (dBuV/m)

5 TEST ITEMS
5.1 Antenna Requirements
5.1.1
Relevant Standards
FCC §15.203 & 15.247(b); RSS-247, 5.4 (6)
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 an antenna that uses a
unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section.
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 or electrical connector is prohibited. This requirement does not apply to carrier current
devices or to devices operated under the provisions of § 15.211, § 15.213, § 15.217, § 15.219, or § 15.221. Further,
this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter
protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with
§ 15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that
the proper antenna is employed so that the limits in this part are not exceeded.
If directional gain of transmitting antennas is greater than 6 dBi, the power shall be reduced by the same level in
dB comparing to gain minus 6 dBi. For the fixed point-to-point operation, the power shall be reduced by one dB for
every 3 dB that the directional gain of the antenna exceeds 6 dBi. The use of a permanently attached antenna or
of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with
the FCC rule.

Conducted Emissions
Note 1: The EUT is working in the Normal link mode.
Note 2: Devices subject to Part 15 must be tested for all available U.S. voltages and frequencies (such as a nominal
120 VAC, 60 Hz and 240 VAC, 50 Hz) for which the device is capable of operation. So, The configuration 120 VAC,
60 Hz and 240 VAC, 50 Hz were tested respectively, but only the worst configuration (120 VAC, 60 Hz ) shown
here.

Test Data and Plots
Note 1: The symbol of “--” in the table which means not application.
Note 2: For the test data above 1 GHz, according the ANSI C63.10-2013, where limits are specified for both average
and peak (or quasi-peak) detector functions, if the peak (or quasi-peak) measured value complies with the average
limit, it is unnecessary to perform an average measurement.
Note 3: The EUT is working in the Normal link mode below 1 GHz.
The low frequency, which started from 9 kHz to 30 MHz, was pre-scanned and the result which was 20 dB lower
than the limit line per 15.31(o) was not reported.

A.9 Band Edge (Restricted-band band-edge)
Note 1: The lowest and highest channels are tested to verify the band edge emissions. Please refer to the following
the plots for emissions values.
Note 2: The test data all are tested in the vertical and horizontal antenna which the trace is max hold. So these
plots have shown the worst case.
Note 3: According the ANSI C63.10-2013, where limits are specified for both average and peak (or quasi-peak)
detector functions, if the peak (or quasi-peak) measured value complies with the average limit, it is unnecessary
to perform an average measurement.
