Band EDGE test 7.1 Measurement Procedure The EUT was placed on a styrofoam table which is 1.5m above ground plane. The measurement procedure at the ban edges was simplified by performing the measurement in just one plot. Both, the in-band-emission and the unwanted emission were be encompassed by the span. After trace stabilization, the maximum peak was be determined by a peak detector and the value was marked by an appropriate limit line. The second limit line, which is 20dB below the first, marks the limit for the emissions in the unrestricted band. A maximum-peak-detector marks the highest emission in the unrestricted band next to the band edge. The measurements were performed at the lower end of the 2.4GHz band. Use the following spectrum analyzer settings: When spectrum scanned above 1GHz setting resolution bandwidth 1MHz, video bandwidth 3MHz: EMI Test Receiver Attenuation RB VB Detector Trace Setting Auto 1MHz 3MHz Peak Max hold When spectrum scanned above 1GHz setting resolution bandwidth 1MHz, video bandwidth 10Hz: EMI Test Receiver Attenuation RB VB Detector Trace TRF No. FCC Part 15.249/A Setting Auto 1MHz 10Hz Peak Max hold Page 14 of 36 Report No. ES181204013E Ver.1.0 7.2 Test SET-UP (Block Diagram of Configuration) Rx Antenna Bore Sight Antenna Mast 3m Ant. feed point 4m Turntable EUT 1.5 m Amplifier Test Receiver 7.3 Measurement Equipment Used: Item Equipment Manufacturer Model No. Serial No. Signal Analyzer Rohde & Schwarz FSV30 103040 Horn Antenna Schwarzbeck BBHA9120D LUNAR EM LNA1G18-40 H+S CBL-26 Power Amplifier Cable 9120D-12 72 J1010000 0081 N/A Cable H+S CBL-26 N/A Cable H+S CBL-26 N/A Characteristics 9KHz-40GHz 1GHz-18GHz Last Cal.

Radiated Emission Test 8.1 Measurement Procedure 1. Below 1000MHz, The EUT was placed on a turn table which is 0.8m above ground plane. And above 1000MHz, The EUT was placed on a styrofoam table which is 1.5m above ground plane. 2. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a variable height antenna tower. 3. For each suspected emission, the EUT was arranged to its worst case and then tune the Antenna tower (From 1m to 4m) and turntable (from 0 degree to 360 degree) to find the maximum reading. A pre-amp and a high pass filter are used for the test in order to get better signal level to comply with the guidelines. 4. Set to the maximum power setting and enable the EUT transmit continuously. 5. Final measurement (Above 1GHz): The frequency range will be divided into different sub ranges depending of the frequency range of the used horn antenna. The EMI Receiver set to peak and average mode and a resolution bandwidth of 1MHz. The measurement will be performed in horizontal and vertical polarization of the measuring antenna and while rotating the EUT in its vertical axis in the range of 0 degree to 360 degree in order to have the antenna inside the cone of radiation. 6. Test Procedure of measurement (For Above 1GHz): 1) Monitor the frequency range at horizontal polarization and move the antenna over all sides of the EUT(if necessary move the EUT to another orthogonal axis). 2) Change the antenna polarization and repeat 1) with vertical polarization. 3) Make a hardcopy of the spectrum. 4) Measure the frequency of the detected emissions with a lower span and resolution bandwidth to increase the accuracy and note the frequency value. 5) Change the analyser mode to Clear/ Write and found the cone of emission. 6) Rotate and move the EUT, so that the measuring distance can be enlarged to 3m and the antenna will be still inside the cone of emission. 7) Measure the level of the detected frequency with the correct resolution bandwidth, with the antenna polarization and azimuth and the peak and average detector, which causes the maximum emission. 8) Repeat steps 1) to 7) for the next antenna spot if the EUT is larger than the antenna beamwidth.

Antenna requirement 9.1 Limit Except for special regulations, the Low-power Radio-Frequency Devices must not be equipped with any jacket for installing an antenna with extension cable. 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 manufacture 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. 9.2 Result The EUT’s antenna, permanent attached antenna, used a Internal antenna, The antenna’s gain is 0 dBi and meets the requirement.
