Number Of Hopping Frequency 13.1 Block Diagram Of Test Setup 13.2 Limit Frequency hopping systems in the 2400-2483.5 MHz band shall use at least 15 channels. 13.3 Test procedure 1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port to the spectrum. 2. Set the spectrum analyzer: RBW = 100kHz. VBW = 300kHz. Sweep = auto; Detector Function = Peak. Trace = Max hold. 3. Allow the trace to stabilize. It may prove necessary to break the span up to sections. in order to clearly show all of the hopping frequencies. The limit is specified in one of the subparagraphs of this Section. 4. Set the spectrum analyzer: Start Frequency = 2.4GHz, Stop Frequency = 2.4835GHz. Sweep=auto; 13.4 Test Result Condition Mode Hopping Number Limit Verdict NVNT 1-DH1 79 15 Pass NVNT 2-DH1 79 15 Pass NVNT 3-DH1 79 15 Pass Report No.:BCTC2309740639-1E No.：BCTC/RF-EMC-005 Page: 67 of 79 Edition：B.1 Test Graphs Hopping No. NVNT 1-DH1 2441MHz Hopping No. NVNT 2-DH1 2441MHz Report No.:BCTC2309740639-1E No.：BCTC/RF-EMC-005 Page: 68 of 79 Edition：B.1 Hopping No. NVNT 3-DH1 2441MHz Report No.:BCTC2309740639-1E No.：BCTC/RF-EMC-005 Page: 69 of 79 Edition：B.1 14. Dwell Time 14.1 Block Diagram Of Test Setup 14.2 Limit Frequency hopping systems in the 2400-2483.5 MHz band shall use at least 15 channels. The average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of 0.4 seconds multiplied by the number of hopping channels employed. Frequency hopping systems may avoid or suppress transmissions on a particular hopping frequency provided that a minimum of 15 channels are used. 14.3 Test procedure 1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port to the spectrum. 2. Set spectrum analyzer span = 0. Centred on a hopping channel; 3. Set RBW = 1MHz and VBW = 3MHz.Sweep = as necessary to capture the entire dwell time per hopping channel. Set the EUT for DH5, DH3 and DH1 packet transmitting. 4. Use the marker-delta function to determine the dwell time. If this value varies with different modes of operation (e.g.. data rate. modulation format. etc.). repeat this test for each variation. The limit is specified in one of the subparagraphs of this Section. Submit this plot(s). 14.4 Test Result DH5 Packet permit maximum 1600 / 79 / 6 hops per second in each channel (5 time slots RX, 1 time slot TX). DH3 Packet permit maximum 1600 / 79 / 4 hops per second in each channel (3 time slots RX, 1 time slot TX). DH1 Packet permit maximum 1600 / 79 /2 hops per second in each channel (1 time slot RX, 1 time slot TX). So, the Dwell Time can be calculated as follows: DH5:1600/79/6*0.4*79*(MkrDelta)/1000 DH3:1600/79/4*0.4*79*(MkrDelta)/1000 DH1:1600/79/2*0.4*79*(MkrDelta)/1000 Remark: Mkr Delta is once pulse time.
