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 C63.10-2013. 2 Support equipment, if needed, was placed as per ANSI C63.10-2013 3 All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10-2013 4 The EUT received power from adapter, the adapter received AC120V/60Hz and AC 240V/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. 8 During the above scans, the emissions were maximized by cable manipulation.

AC Power Conducted Emission Limit

TEST PROCEDURE

1. The EUT was placed on a turn table which is 0.8m above ground plane when testing

frequency range 9 KHz ­1GHz;the EUT was placed on a turn table which is 1.5m above

ground plane when testing frequency range 1GHz ­ 25GHz.

2. Maximum procedure was performed by raising the receiving antenna from 1m to 4m and

rotating the turn table from 0° to 360° to acquire the highest emissions from EUT.

3. And also, each emission was to be maximized by changing the polarization of receiving

antenna both horizontal and vertical.

4. Repeat above procedures until all frequency measurements have been completed.

5. Radiated emission test frequency band from 9KHz to 25GHz.

Field Strength Calculation

The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting the Amplifier Gain and Duty Cycle Correction Factor(if any) from the measured reading. The basic equation with a sample calculation is as follows:

FS = RA + AF + CL - AG

Where FS = Field Strength RA = Reading Amplitude AF = Antenna Factor

CL = Cable Attenuation Factor (Cable Loss) AG = Amplifier Gain

Transd=AF +CL-AG

RADIATION LIMIT

For intentional device, according to § 15.209(a), the general requirement of field strength of radiated emission from intentional radiators at a distance of 3 meters shall not exceed the following table. According to § 15.247(d), in any 100kHz bandwidth outside the frequency band in which the EUT is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20dB below that in the100kHz bandwidth within the band that contains the highest level of desired power.

The pre-test have done for the EUT in three axes and found the worst emission at position shown in test setup photos.

position. 2. We measured Radiated Emission at GFSK,/4 DQPSK mode from 9 KHz to 25GHz and recorded worst
case at GFSK DH5 mode. 3. For below 1GHz testing recorded worst at GFSK DH5 middle channel. 4. Radiated emission test from 9 KHz to 10th harmonic of fundamental was verified, and no emission found
except system noise floor in 9 KHz to 30MHz and not recorded in this report.

4.8 Out-of-band Emissions
Limit In any 100 kHz 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 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power, based on either an RF con-ducted or a radiated measurement, pro-vided the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter com-plies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required.
Test Procedure
Connect the transmitter output to spectrum analyzer using a low loss RF cable, and set the spectrum analyzer to RBW=100 kHz, VBW= 300 kHz, peak detector , and max hold. Measurements utilizing these setting are made of the in-band reference level, bandedge and out-of-band emissions.
