No.I19Z60710-IOT02 Page70of87 A.7. 20dB Bandwidth Method of Measurement: See ANSI C63.10-clause 6.9.2 Measurement Procedure - Unwanted Emissions 1. Set RBW = 30kHz. 2. Set VBW = 100 kHz. 3. Set span to 3MHz 4. Detector = peak. 5. Trace Mode = max hold. 6. Sweep = auto couple. 7. Allow the trace to stabilize (this may take some time, depending on the extent of the span). Measurement Limit: Standard Limit FCC 47 CFR Part 15.247(a)(1) NA﹡ Use NdB Down function of the SA to measure the 20dB Bandwidth ﹡Comment: This test case is not required according to the latest FCC 47 CFR Part 15.247. But the test results are necessary for “carrier frequency separation” test case, in Annex A.8. Measurement Results: For GFSK Channel 20dB Bandwidth (kHz) Conclusion 0 Fig.82 944.25 NA 39 Fig.83 950.25 NA 78 Fig.84 943.50 NA Forπ/4 DQPSK Channel 20dB Bandwidth (kHz) Conclusion 0 Fig.85 1271.25 NA 39 Fig.86 1276.50 NA 78 Fig.87 1274.25 NA For 8DPSK Channel 20dB Bandwidth (kHz) Conclusion 0 Fig.88 1291.50 NA 39 Fig.89 1275.75 NA 78 Fig.90 1270.50 NA Conclusion: NA Test graphs as below: ©Copyright.

No.I19Z60710-IOT02 Page76of87 A.8. Carrier Frequency Separation Method of Measurement: See ANSI C63.10-clause 7.8.2 The EUT must have its hopping function enabled. Use the following spectrum analyzer settings:  Span = 3MHz  RBW=300kHz  VBW=300kHz  Sweep = auto  Detector function = peak  Trace = max hold  Allow the trace to stabilize Search the peak marks of the middle frequency and adjacent channel, then record the separation between them. ﹡Comment: This limit should be over 25 kHz or (2/3) * 20dB bandwidth, whichever is greater. Measurement Limit: Standard Limit(kHz) FCC 47 CFR Part 15.247(a)(1) over 25 kHz or (2/3) * 20dB bandwidth Measurement Result: For GFSK Channel Carrier frequency separation (kHz) Conclusion 39 Fig.91 1003.50 P For π/4 DQPSK Channel Carrier frequency separation (kHz) Conclusion 39 Fig.92 1299.75 P For 8DPSK Channel Carrier frequency separation (kHz) Conclusion 39 Fig.93 1329.75 P Conclusion: PASS Test graphs as below: ©Copyright.

No.I19Z60710-IOT02 Page79of87 A.9. Number of Hopping Channels Method of Measurement: See ANSI C63.10-clause 7.8.3 The EUT must have its hopping function enabled. Use the following spectrum analyzer settings:  Span = the frequency band of operation  RBW = 500kHz  VBW = 500kHz  Sweep = auto  Detector function = peak  Trace = max hold  Allow the trace to stabilize It might prove necessary to break the span up into subranges to show clearly all of the hopping frequencies. Compliance of an EUT with the appropriate regulatory limit shall be determined for the number of hopping channels. A plot of the data shall be included in the test report. Measurement Limit: Standard Limit FCC 47 CFR Part 15.247(a) (1)(iii) At least 15 non-overlapping channels Measurement Result: For GFSK Channel Number of hopping channels Conclusion 0~39 Fig.94 79 P 40~78 Fig.95 Forπ/4 DQPSK Channel Number of hopping channels Conclusion 0~39 Fig.96 79 P 40~78 Fig.97 For 8DPSK Channel Number of hopping channels Conclusion 0~39 Fig.98 79 P 40~78 Fig.99 Conclusion: PASS Test graphs as below: ©Copyright.
