Page 27 of 50 Report No.: HK2606050604-E 4.4 Maximum Peak Output Power Measurement 4.4.1 Limit The Maximum Peak Output Power Measurement is 30dBm. 4.4.2 Test Procedure The maximum peak conducted output power may be measured using a broadband peak RF automatic control unit. The RF automatic control unit shall have a video bandwidth that is greater than or equal to the DTS bandwidth and shall utilize a fast-responding diode detector. The maximum Average conducted output power may be measured using a wideband RF automatic control unit with a thermocouple detector or equivalent. The RF automatic control unit shall have a video bandwidth that is greater than or equal to the DTS bandwidth and shall utilize a fast-responding diode detector. 4.4.3 Deviation from Standard No deviation. 4.4.4 Test Setup 4.4.5 Test Results Test Rate Channel Channel Frequency (MHz) Maximum Peak Conducted Output Power (dBm) Limit (dBm) Result 1M CH00 2402 -0.25 30.00 Pass CH19 2440 0.35 Pass CH39 2480 0.96 Pass 2M CH00 2402 -0.26 30.00 Pass CH19 2440 0.32 Pass CH39 2480 0.96 Pass Note: The test results including the cable loss. Page 28 of 50 Report No.: HK2606050604-E 4.5 Power Spectral Density 4.5.1 Limit For digitally modulated systems, the power spectral density conducted from the intentional radiator to the antenna shall not be greater than 8dBm in any 3 kHz band during any time interval of continuous transmission. 4.5.2 Test Procedure Use this procedure when the maximum peak conducted output power in the fundamental emission is used to demonstrate compliance. Set the RBW =3 kHz. Set the VBW =10 KHz. Set the span to 1.5 times the DTS channel bandwidth. Detector = peak. Sweep time = auto couple. Trace mode = max hold. Allow trace to fully stabilize. Use the peak marker function to determine the maximum power level. If measured value exceeds limit, reduce RBW (no less than 3 kHz) and repeat. The resulting peak PSD level must be 8dBm. 4.5.3 Deviation from Standard No deviation. 4.5.4 Test Setup EUT SPECTRUM ANALYZER Page 29 of 50 Report No.: HK2606050604-E 4.5.5 Test Results Test Rate Channel Channel Frequency (MHz) Result (dBm/3KHz) 1M CH00 2402 -14.44 CH19 2440 -14.00 CH39 2480 -13.58 2M CH00 2402 -14.60 CH19 2440 -14.44 CH39 2480 -13.79 Limit : 8dBm/3KHz Test Result PASS 1M: CH00 Page 30 of 50 Report No.: HK2606050604-E 1M: CH19 1M: CH39 Page 31 of 50 Report No.: HK2606050604-E 2M: CH00 2M: CH19 Page 32 of 50 Report No.: HK2606050604-E 2M: CH39 Page 33 of 50 Report No.: HK2606050604-E 4.6 6dB Bandwidth 4.6.1 Limit For digital modulation systems, the minimum 6 dB bandwidth shall be at least 500 kHz. 4.6.2 Test Procedure The transmitter output was connected to the spectrum analyzer through an attenuator. The bandwidth of the fundamental frequency was measured by spectrum analyzer with RBW=100 KHz and VBW=300 KHz. The 6dB bandwidth is defined as the total spectrum the power of which is higher than peak power minus 6dB. 1. Set RBW = 100 kHz. 2. Set the video bandwidth (VBW) ≥ 3 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. 4.6.3 Deviation from Standard No deviation. 4.6.4 Test Setup EUT SPECTRUM ANALYZER 4.6.5 Test Result Test Rate Channel Channel Frequency (MHz) 6dB Bandwidth (MHz) Limit (KHz) Result 1M CH00 2402 0.676 ≥500 Pass CH19 2440 0.680 Pass CH39 2480 0.664 Pass 2M CH00 2402 1.128 ≥500 Pass CH19 2440 1.120 Pass CH39 2480 1.156 Pass Page 34 of 50 Report No.: HK2606050604-E 1M: CH00 1M: CH19 Page 35 of 50 Report No.: HK2606050604-E 1M: CH39 2M: CH00 Page 36 of 50 Report No.: HK2606050604-E 2M: CH19 2M: CH39 Page 37 of 50 Report No.: HK2606050604-E 4.7 Occupied Bandwidth 4.7.1 Test Procedure The occupied bandwidth is the frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers are each equal to 0.5% of the total mean power of the given emission. The following procedure shall be used for measuring 99% power bandwidth: RBW=1% to 5% of the OBW VBW=approximately 3 X RBW Detector=Peak Trace Mode: Max Hold Use the 99% power bandwidth function of the instrument to measure the Occupied Bandwidth and recorded. 4.7.2 Deviation from Standard No deviation. 4.7.3 Test Setup EUT SPECTRUM ANALYZER 4.7.4 Test Result N/A Page 38 of 50 Report No.: HK2606050604-E 4.8 Band Edge 4.8.1 Limit 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 FCC rules in section 5.8.1, the attenuation required shall be 30 dB instead of 20 dB. 4.8.2 Test Procedure a. The EUT was directly connected to the spectrum analyzer and antenna output port as show in the block diagram below. b. Span = wide enough to capture the peak level of the emission operating on the channel closest to the band edge, as well as any modulation products which fall outside of the authorized band of operation, RBW  1% of the span, VBW  RBW, Sweep = auto, Detector function = peak, Trace = max hold. 4.8.3 Deviation from Standard No deviation. 4.8.4 Test Setup Page 39 of 50 Report No.: HK2606050604-E 4.8.5 Test Results PASS 1M: CH00 CH39 Page 40 of 50 Report No.: HK2606050604-E 2M: CH00 CH39 Page 41 of 50 Report No.: HK2606050604-E 4.9 Conducted Spurious Emissions 4.9.1 Applied Procedures / Limit…
