In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated device is operating, the RF power that is produced 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 that the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of root-mean-square averaging over a time interval, as permitted under Section 5.4(4), the attenuation required shall be 30 dB instead of 20 dB. Attenuation below the general field strength limits specified in RSS-Gen is not required. Test Settings: Center frequency = the highest, middle and the lowest channels a) RBW = 100 kHz b) VBW ≥ 3 x RBW c) Detector = peak d) Sweep time = auto couple e) Trace mode= max hold f) Allow trace to fully stabilize g) Use the peak marker function to determine the maximum amplitude level. Limit : Emission level < 20 dBc Test results: Complies - All conducted emission in any 100kHz bandwidth outside of the spread spectrum band was at least 20dB lower than the highest in-band spectral density. Therefore the applying equipment meets the requirement. See next pages for actual measured spectrum plots. CTK-D151-06 R101 Rev.0

The center of the Loop Test Antenna is 1m above the ground. During the measurement the Loop Test Antenna rotates about its vertical axis for maximum response at each azimuth about the EUT. 2) In the frequency rage above 30 MHz, Bi—Log Test Antenna(30 MHz to 1 GHz) and Horn Test Antenna(above 1 GHz) are used. Test Antenna is 3m away from the EUT. Test Antenna height is carried from 1m to 4m above the ground to determine the maximum value of the field strength. The emissions levels at both horizontal and vertical polarizations should be tested. Instrument Settings Frequency Range = 9 kHz ~ 25 GHz (2.4 GHz 10°" harmonic) a) RBW = 1 MHz forf > 1 GHz, 100 kHz for f < 1 GHz, 9 kHz for f < 30 MHz b) VBW > RBW c) Sweep time = auto couple CTK—D151—06 R101 Rev.0

General Field Strength Limits for Licence-Exempt Transmitters Field Strength Field Strength Measurement Frequency(MHz) uV/m@3m dBuV/m@3m Distance (meters) 0.009-0.490 2400/F(kHz) - 300 0.490-1.705 24000/F(kHz) - 30 1.705-30 30 - 30 30-88 100** 40 3 88-216 150** 43.5 3 216-960 200** 46 3 Above 960 500 54 3 ** Except as provided in 15.209(g).fundamental emissions from intentional radiators operating under this Section shall not be located in the frequency bands 54-72MHz, 76- 88MHz, 174-216MHz, 470-806MHz. However, operation within these frequency bands is permitted under other sections of this Part, e.g.15.231 and 15.241. Note : 1) For above 1 GHz, the emission limit in this paragraph is based on measurement instrumentation employing an average detector, measurement using instrumentation with a peak detector function, corresponding to 20 dB above the maximum permitted average limit. 2) For above 1 GHz, limit field strength of harmonics : 54 dBuV/m@3m (AV) and 74 dBuV/m@3m (PK) 3) For measurement above 1GHz, the resolution bandwidth is set to 1 MHz and video bandwidth is set to 1 MHz for peak measurement and 10 Hz for average measurement.(Duty Cycle is > 98%,) 4) Duty Cycle is < 98%, VBW setting will need to > 1/T.
