NUMBER OF HOPPING FREQUENCY MEASUREMENT 10.1 Provisions Applicable This frequency hopping system must employ a minimum of 15 hopping channels. 10.2 Measurement Procedure The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings: 1. Span = The frequency band of operation. Depending on the number of channels the device 2. supports, it may be necessary to divide the frequency range of operation across multiple spans, to allow the individual channels to be clearly seen. 3. RBW: To identify clearly the individual channels, set the RBW to less than 30% of the channel spacing or the 20 dB bandwidth, whichever is smaller. 4. VBW ≥ RBW 5. Sweep time = Auto couple 6. Detector = Peak 7. Trace mode = Max hold 8. Allow the trace to stabilize 10.3 Measurement Setup (Block Diagram of Configuration) 10.4 Measurement Result Test Data of Number of Hopping Frequency Test Mode Number of Hopping Frequency Limits Pass or Fail 8DPSK Hopping 79 >=15 Pass Report No.: AGC11758240103FR01 Page 73 of 83 Test Graphs of Number of Hopping Frequency Test_Graph_EDR_HOP_ANT1_NA_3Mbps_Number of Hopping Note: The 8DPSK modulation is the worst case and recorded in the report. Report No.: AGC11758240103FR01 Page 74 of 83 11. TIME OF OCCUPANCY (DWELL TIME) MEASUREMENT 11.1 Provisions Applicable The maximum permissible time of occupancy is 400ms within a period of 400ms multiplied by the number of hopping channels employed. 11.2 Measurement Procedure The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings: 1. Span = Zero span, centered on a hopping channel. 2. RBW shall be ≤ channel spacing and where possible RBW should be set >> 1 / T, where T is the expected dwell time per channel. 3. VBW ≥ RBW 4. Sweep time = As necessary to capture the entire dwell time per hopping channel 5. Detector = Peak 6. Trace mode = Free Run 7. Use the marker-delta function to determine the transmit time per hop. If this value varies with different modes of operation (data rate, modulation format, number of hopping channels, etc.), then repeat this test for each variation in transmit time. An oscilloscope may be used instead of a spectrum analyzer. The EUT shall show compliance with the appropriate regulatory limit for the number of hopping channels. A plot of the data shall be included in the test report. 11.3 Measurement Setup (Block Diagram of Configuration) 11.4 Measurement Result Test Data of Dwell Time Channel Time of Pulse for 3DH5 (ms) Number of hops in the period specified in the requirements Dwell Time (ms) Limit (ms) Pass or Fail 2402 2.894 21.0*4 243.096 400 Pass 2441 2.894 27.0*4 312.552 400 Pass 2480 2.894 27.0*4 312.552 400 Pass Report No.: AGC11758240103FR01 Page 75 of 83 Test Graphs of Dwell Time Test_Graph_EDR_HOP_ANT1_NA_3Mbps_2402_Number of Busrt Test_Graph_EDR_HOP_ANT1_NA_3Mbps_2402_Time per Burst Report No.: AGC11758240103FR01 Page 76 of 83 Test_Graph_EDR_HOP_ANT1_NA_3Mbps_2441_Number of Busrt Test_Graph_EDR_HOP_ANT1_NA_3Mbps_2441_Time per Burst Report No.: AGC11758240103FR01 Page 77 of 83 Test_Graph_EDR_HOP_ANT1_NA_3Mbps_2480_Number of Busrt Test_Graph_EDR_HOP_ANT1_NA_3Mbps_2480_Time per Burst Note: All mode rates are tested and evaluated, 8DPSK modulated 3DH5 mode is the worst case and documented in the report. Report No.: AGC11758240103FR01 Page 78 of 83 12. FREQUENCY SEPARATION MEASUREMENT 12.1 Provisions Applicable When the power is less than 0.125W: The minimum permissible channel separation for this system is 2/3 the value of the 20dB BW. When the power is less than 1W: The minimum permissible channel separation for this system is 20dB BW. 12.2 Measurement Procedure The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings: 1. Span: Wide enough to capture the peaks of two adjacent channels. 2. RBW: Start with the RBW set to approximately 30% of the channel spacing; adjust as necessary to best identify the center of each individual channel. 3. Video (or average) bandwidth (VBW) ≥ RBW. 4. Sweep: Auto. 5. Detector function: Peak. 6. Trace: Max hold. g) Allow the trace to stabilize. 7. Use the marker-delta function to determine the separation between the peaks of the adjacent channels. 12.3 Measurement Setup (Block Diagram of Configuration) 12.4 Measurement Result Test Data of Frequency Separation Test Mode Channel Separation (MHz) Limits (MHz) Pass or Fail 8DPSK Hopping 1.009 ≥0.792 Pass Report No.: AGC11758240103FR01 Page 79 of 83 Test Graphs of Number of Hopping Frequency Test_Graph_EDR_HOP_ANT1_NA_3Mbps_Hopping Separation Note: The 8DPSK modulation is the worst case and recorded in the report.
