3. Conducted Emission Test
3.1 Conducted Power Line Emission Limit
For unintentional device, according to § 15.107(a) Line Conducted Emission Limits is as following
* Decreasing linearly with the logarithm of the frequency
For intentional device, according to §15.207(a) Line Conducted Emission Limit is same as above table.
3.2 Test Setup
3.3 Test Procedure
1, The equipment was set up as per the test configuration to simulate typical actual usage per the user’s
manual. The EUT is a tabletop system, a wooden table with a height of 0.8 meters is used and is
placed on the ground plane as per ANSI C63.10.
2, Support equipment, if needed, was placed as per ANSI C63.10.
3, All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10.
4, If a EUT received DC power from the USB Port of Notebook PC, the PC’s adapter received
AC120V/60Hz power through a Line Impedance Stabilization Network (LISN) which supplied power
source and was grounded to the ground plane.
5, All support equipments received AC power from a second LISN, if any.
6, The EUT test program was started. Emissions were measured on each current carrying line of the EUT
using a spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has two
monitoring points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line 1
connected to Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1
connected to a 50 ohm load and Line 2 connected to the Analyzer / Receiver.
7, Analyzer / Receiver scanned from 150 KHz to 30MHz for emissions in each of the test modes.
3.4 Test Data
Not applicable for device which is DC Power supply.

4. Radiated Emissions
4.1. Standard Applicable
According to §15.231(b), the field strength of emissions from intentional radiators operated under this
section shall not exceed the following:
The limits on the field strength of the spurious emissions in the above table are based on the
fundamental frequency of the intentional radiator. Spurious emissions shall be attenuated to the average
(or, alternatively, CISPR quasi-peak) limits shown in this table or to the general limits shown in §15.209,
whichever limit permits a higher field strength.
The emission limit in this paragraph is based on measurement instrumentation employing an average
detector. The provisions in §15.35 for limiting peak emissions apply. Spurious Radiated Emissions
measurements starting below or at the lowest crystal frequency.
Compliance with the provisions of §15.205 shall be demonstrated using the measurement
instrumentation specified in that section.
4.2. Test Procedure
The setup of EUT is according with per ANSI C63.10-2013 measurement procedure. The specification
used was with the FCC Part 15.205 15.231(b) and FCC Part 15.209 Limit.

4.3. Corrected Amplitude & Margin Calculation
The Corrected Amplitude is calculated by adding the Antenna Factor and the Cable Factor, and subtracting the Amplifier
Gain from the Amplitude reading. The basic equation is as follows:
Corr. Ampl. = Indicated Reading +Ant.Loss +Cab. Loss – Ampl.Gain
The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit.For example,
a margin of -6dB V means the emission is 6dB V below the maximum limit. The equation for margin calculation is as
follows:
Margin = Corr. Ampl. – FCC Part 15C Limit
4.4. Environmental Conditions
Temperature:

6.1. Standard Applicable
According to FCC Part 15.231(a), the transmitter shall be complied the following requirements:
(1) A manually operated transmitter shall employ a switch that will automatically deactivate the
transmitter within not more than 5 seconds of being released.
(2) A transmitter activated automatically shall cease transmission within 5 seconds after activation.
(3) Periodic transmissions at regular predetermined intervals are not permitted. However, polling or

7. Duty Cycle
7.1. Standard Applicable
According to FCC Part 15.231(b)(2) and 15.35 (c),For pulse operation transmitter, the averaging pulsed
emissions are calculated by peak value of measured emission plus duty cycle factor.
7.2. Test Procedure
1) The EUT was placed on a turntable which is 0.8m above ground plane.
2) Set EUT operating in continuous transmitting mode
3) Set Test Receiver into spectrum analyzer mode, Tune the spectrum analyzer to the transmitter carrier
frequency, and set the spectrum analyzer resolution bandwidth(RBW) to 1000kHz and video
bandwidth(VBW) to 1000kHz, Span was set to 0Hz.
4) The Duty Cycle was measured and recorded.
7.4. INTRODUCTION TO PDCF reference:
(§15.35 Measurement detector functions and bandwidths.)
1) Part 15 of the FCC Rules provides for the operation of low power communication devices without an
individual license (e.g., intrusion detectors, pulsed water tank level gauges, etc.), subject to certain
requirements. Some of these devices use extremely narrow pulses to generate wideband emissions,
which are measured to determine compliance with the rules. These measurements are typically
performed with a receiver or spectrum analyzer. Depending on a number of factors (e.g., resolution
bandwidth, pulsewidth, etc.), the spectrum analyzer may not always display the true peak value of the
measured emission. This effect, called “pulse desensitization,” relates to the capabilities of the
measuring instrument. For the measurement and reporting of the true peak of pulsed emissions, it may
be necessary to apply a “pulse desensitization correction factor” (PDCF) to the measured value,
pursuant to 47 CFR 15.35(a).

Report No.: HK1812181967-E
If using spectrum analyzer to measure pulse signal , it have to make sure the RBW use is at least 2/PW.
•When RBW is less than 2/PW, you are able to measure the true peak level of the pulse signal. If this is
the case ,
PDCF is required to compensate to determine true peak value.
Pulse desensitization:
PW =28840usec (5000* 4+ 520*17), Period=74500usec, Level=A
RBW>2/PW=0.07K, 1/T=0.13K
NOTE: 2 / PW < RBW, first don't need
2). For the actual test, please refer to the ANSI C63.10,Annex C refer to section 5 for more detail
