The field strength of radiation emission was measured in the following position: EUT stand-up position (Y
axis), lie-down position (X, Z axis).
The following data show only with the worst case setup.
The worst case of Y axis was reported.
Based on client request, all normal using modes of the normal function were tested but only the worst test
data of the worst mode is reported by this report.

Remark:
All of the modulation modes, Top Channel, Middle Channel and Bottom Channel have been tested, the worst
case mode is TM1(1Mbps, GFSK) reported in this report.


2.5. EUT configuration

The following peripheral devices and interface cables were connected during the measurement:

4. TEST CONDITIONS AND RESULTS
4.1. Conducted Emissions Test

TEST CONFIGURATION




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 C63.4.

2 Support equipment, if needed, was placed as per ANSI C63.4.

3 All I/O cables were positioned to simulate typical actual usage as per ANSI C63.4.

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.

8 During the above scans, the emissions were maximized by cable manipulation.

The RBW/VBW for 150KHz to 30MHz: 9KHz

              FS = RA + AF + CL - AG




        Where FS = Field Strength                                 CL = Cable Attenuation Factor (Cable Loss)
             RA = Reading Amplitude                               AG = Amplifier Gain
             AF = Antenna Factor

4.3. Band Edge Measurement

TEST CONFIGURATION

Same as Section 4.2

TEST PROCEDURE

The band edge compliance of RF radiated emission should be measured by following the guidance in ANSI
C63.4 with respect to maximizing the emission by rotating the EUT, measuring the emission while the EUT is
situated in three orthogonal planes (if appropriate), adjusting the measurement antenna height and
polarization etc. Set RBW to 100KHz and VBM to 300KHz to measure the peak field strength and set
RBW to 1MHz and VBW to 10Hz to measure the average radiated field strength.
The conducted RF band edge was measured by using a spectrum analyzer. Set span wide enough to capture
the highest in-band emission and the emission at the band edge. Set RBW to 100 KHz and VBM to 300 KHz,
to measure the conducted peak band edge.


LIMIT
FCC PART 15.249(d) Emissions radiated outside of the specified frequency bands, except for harmonics,
shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission
limits in §15.209, whichever is the lesser attenuation.

TEST RESULTS
Radiated Test:
Operation Mode: TX on Bot Channel
Polarity: Hor.


 V1.0                                    Page 18 of 28                  Report No.: CTL1401150079-WF

Operation Mode: TX on Bot Channel
Polarity: Ver.




Note:

1. The field strength of any emissions which appear outside of this band shall not exceed the general radiated
   emission limits in Section 15.209.

2. The average measurement was not performed when the peak measured data under the limit of average
   detection.

5. Antenna Requirement
Standard Applicable

For intentional device, according to FCC 47 CFR Section 15.203, 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.

And according to FCC 47 CFR Section 15.247 (c), if transmitting antennas of directional gain greater than
6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna
exceeds 6dBi.

Refer to statement below for compliance.

The manufacturer may design the unit so that the user can replace a broken antenna, but the use of a
standard antenna jack or electrical connector is prohibited. Further, this requirement does not apply to
intentional radiators that must be professionally installed.

Antenna Connected Construction

The antenna used in this product is a PCB Antenna, The directional gains of antenna used for transmitting is 0
dBi.
