16 3.2.2 TEST PROCEDURE Below 1GHz test procedure as below: a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter semi-anechoic camber. The table was rotated 360 degrees to determine the position of the highest radiation. b. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top of a variable-height antenna tower. c. The antenna height is varied from one meter to four meters above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set to make the measurement. d. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from 1 meter to 4 meters (for the test frequency of below 30MHz, the antenna was tuned to heights 1 meter) and the rotatable table was turned from 0 degrees to 360 degrees to find the maximum reading. e. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode. f. If the emission level of the EUT in peak mode was 10dB lower than the limit specified, then testing could be stopped and the peak values of the EUT would be reported. Otherwise the emissions that did not have 10dB margin would be re-tested one by one using peak, quasi-peak or average method as specified and then reported in a data sheet. Above 1GHz test procedure as below: g. Different between above is the test site, change from Semi- Anechoic Chamber to fully Anechoic Chamber and change form table 0.8 metre to 1.5 metre( Above 18GHz the distance is 1 meter and table is 1.5 metre). h. Test the EUT in the lowest channel,the middle channel,the Highest channel Note: Both horizontal and vertical antenna polarities were tested and performed pretest to three orthogonal axis.

BANDWIDTH TEST 5.1 APPLIED PROCEDURES / LIMIT FCC Part15 (15.247), Subpart C Section Test Item Limit Frequency Range (MHz) Result (a)(2) Bandwidth >= 500KHz (6dB bandwidth) PASS TEST PROCEDURE 1. Set RBW = 100 khz. 2. Set the video bandwidth (VBW) 3 x RBW. 3. Detector = Peak. 4. Trace mode = max hold. 5. Sweep = auto couple. 6. Allow the trace to stabilize. 7. Measure the maximum width of the emission that is constrained by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 db relative to the maximum level measured in the fundamental emission DEVIATION FROM STANDARD No deviation TEST SETUP EUT OPERATION CONDITIONS The EUT tested system was configured as the statements of 2.4 Unless otherwise a special operating condition is specified in the follows during the testing.

52 KHZ BANDWIDTH OF FREQUENCY BAND EDGE 7.1 APPLICABLE STANDARD 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 (a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in (a), must also comply with the radiated emission limits specified in (a) (see (c)). 7.2 TEST PROCEDURE a) Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. b) Position the EUT without connection to measurement instrument. Turn on the EUT and connect its antenna terminal to measurement instrument via a low loss cable. Then set it to any one measured frequency within its operating range, and make sure the instrument is operated in its linear range. c) Set RBW to 100 khz and VBW of spectrum analyzer to 300 khz with a convenient frequency span including 100 khz bandwidth from band edge. d) 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. e) Repeat above procedures until all measured frequencies were complete. 7.3 DEVIATION FROM STANDARD No deviation. 7.4 TEST SETUP EMC Report Tel: Web: Page 52 of 61
