Test Procedures 1) Sequence of testing 9 kHz to 30 MHz Setup: --- The equipment was set up to simulate a typical usage like described in the user manual or described by manufacturer. --- If the EUT is a tabletop system, a rotatable table with 0.8 m height is used. --- If the EUT is a floor standing device, it is placed on the ground. --- Auxiliary equipment and cables were positioned to simulate normal operation conditions. --- The AC power port of the EUT (if available) is connected to a power outlet below the turntable. --- The measurement distance is 3 meter. --- The EUT was set into operation. Premeasurement: --- The turntable rotates from 0°to 315°using 45°steps. --- The antenna height is 1.0 meter. --- At each turntable position the analyzer sweeps with peak detection to find the maximum of all emissions Final measurement: --- Identified emissions during the premeasurement the software maximizes by rotating the turntable position (0°to 360°) and by rotating the elevation axes (0°to 360°). --- The final measurement will be done in the position (turntable and elevation) causing the highest emissions with QPK detector. --- The final levels, frequency, measuring time, bandwidth, turntable position, correction factor, margin to the limit and limit will be recorded. Also a plot with the graph of the premeasurement and the limit will be stored.

5.8. Band-Edge Measurements For Radiated Emissions
5.8.1. Standard Applicable 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 conducted or a radiated measurement, provided the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies 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. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a) (see §15.205(c)). 5.8.2.

1. The EUT was placed on a turn table which is 1.5m above ground plane. 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. Setting test receiver/spectrum as following table states:

According to KDB 558074 D01 for Antenna-port conducted measurement. Antenna-port conducted measurements may also be used as an alternative to radiated measurements for demonstrating compliance in the restricted frequency bands. If conducted measurements are performed, then proper impedance matching must be ensured and an additional radiated test for cabinet/case spurious emissions is required. 1. Check the calibration of the measuring instrument using either an internal calibrator or a known
signal from an external generator. 2. Remove the antenna from the EUT and then connect to a low loss RF cable from the antenna port
to an EMI test receiver, then turn on the EUT and make it operate in transmitting mode. Then set it to Low Channel and High Channel within its operating range, and make sure the instrument is operated in its linear range. 3. Set both RBW and VBW of spectrum analyzer to 100 kHz with a convenient frequency span including 100kHz bandwidth from band edge, for Radiated emissions restricted band RBW=1MHz, VBW=3MHz for peak detector and RBW=1MHz, VBW=3MHz for AV detector. 4. Measure the highest amplitude appearing on spectral display and set it as a reference level. Plot the graph with marking the highest point and edge frequency. 5. Repeat above procedures until all measured frequencies were complete. 6. Measure the conducted output power (in dBm) using the detector specified by the appropriate regulatory agency (see 12.2.2, 12.2.3, and 12.2.4 for guidance regarding measurement procedures for determining quasi-peak, peak, and average conducted output power, respectively). 7. Add the maximum transmit antenna gain (in dBi) to the measured output power level to determine the EIRP level (see 12.2.5 for guidance on determining the applicable antenna gain) 8. Add the appropriate maximum ground reflection factor to the EIRP level (6 dB for frequencies 30 MHz, 4.7 dB for frequencies between 30 MHz and 1000 MHz, inclusive and 0 dB for frequencies > 1000 MHz). 9. For devices with multiple antenna-ports, measure the power of each individual chain and sum the EIRP of all chains in linear terms (e.g., Watts, mW). 10. Convert the result ant EIRP level to an equivalent electric field strength using the following relationship:

E = EIRP 20log D + 104.77=EIRP+95.23

Where: E = electric field strength in dBV/m, EIRP = equivalent isotropic radiated power in dBm D = specified measurement distance in meters. 11. Since the out-of-band characteristics of the EUT transmit antenna will often be unknown, the use of a conservative antenna gain value is necessary. Thus, when determining the EIRP based on the measured conducted power, the upper bound on antenna gain for a device with a single RF output shall be selected as the maximum in-band gain of the antenna across all operating bands, or 2 dBi, whichever is greater. However, for devices that operate in multiple frequency bands while using
Page 30 of 37

Report No.: TZ0129250202FRF03 the same transmit antenna, the highest gain of the antenna within the operating band nearest in frequency to the restricted band emission being measured may be used in lieu of the overall highest gain when the emission is at a frequency that is within 20 percent of the nearest band edge frequency, but in no case shall a value less than 2 dBi be used. 12. Per KDB662911 D01 section b) In cases where a combination of conducted measurements and cabinet radiated measurements are permitted to demonstrate compliance with absolute radiated out-of-band and spurious limits (e.g., KDB Publications 558074 for DTS and 789033 for U-NII), the conducted measurements must be combined with directional gain to compute the radiated levels of the out-of-band and spurious emissions as described in this section. 13. Compare the resultant electric field strength level to the applicable regulatory limit. 14. Perform radiated spurious emission test duress until all measured frequencies were complete.

5.9. Antenna Requirements

Report No.: TZ0129250202FRF03

5.9.1. Standard Applicable

According to antenna requirement of §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. 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 re-placed 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 Sections 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 Section 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.

And according to §15.247(4)(1), system operating in the 2400-2483.5MHz bands that are used exclusively for fixed, point-to-point operations may employ transmitting antennas with directional gain greater than 6dBi provided the maximum peak output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna exceeds 6dBi.
5.9.2. Antenna Connector Construction
The directional gains of antenna used for transmitting is refer to section 1.1 of this report, and the antenna is an internal antenna connect to PCB board and no consideration of replacement. Please see EUT photo for details.
5.9.3. Results
