Dwell Time 14.1 Block Diagram Of Test Setup 14.2 Limit For frequency hopping systems operating in the 902-928 MHz band: if the 20 dB bandwidth of the hopping channel is less than 250 kHz, the system shall use at least 50 hopping frequencies and the average time of occupancy on any frequency shall not be greater than 0.4 seconds within a 20 second period; if the 20 dB bandwidth of the hopping channel is 250 kHz or greater, the system shall use at least 25 hopping frequencies and the average time of occupancy on any frequency shall not be greater than 0.4 seconds within a 10 second period. The maximum allowed 20 dB bandwidth of the hopping channel is 500 kHz. 14.3 Test procedure 1. The RF output of EUT was connected to the spectrum analyzer by RF cable and attenuator. The path loss was compensated to the results for each measurement. 2. Set to the maximum power setting and enable the EUT transmit continuously. 3. Enable the EUT hopping function. 4. The spectrum analyzer is set to: Center frequency = 914.75MHz, Span = zero RBW = 100 kHz (RBW shall be ≤ channel spacing and where possible RBW should be set >> 1 / T, where T is the expected dwell time per channel), VBW ≥ RBW Detector function = peak, Trace = max hold 5. Measure and record the results in the test report. 14.4 Test Result Antenna Length (ms) Number Dwell time (ms) Limit (ms) Result Antenna 1 40.50 8 324.00 400 PASS Antenna 2 39.80 8 318.40 400 PASS Antenna 3 40.10 8 320.80 400 PASS Antenna 4 40.30 8 322.40 400 PASS Note: Dwell time= Length* Number Report No.: BCTC2407121006E No.：BCTC/RF-EMC-005 Page: 64 of 70 Edition：B.2 Antenna 1 Length (Hopping Mode) Period (Hopping Mode) Antenna 2 Length (Hopping Mode) Period (Hopping Mode) Report No.: BCTC2407121006E No.：BCTC/RF-EMC-005 Page: 65 of 70 Edition：B.2 Antenna 3 Length (Hopping Mode) Period (Hopping Mode) Antenna 4 Length (Hopping Mode) Period (Hopping Mode) Report No.: BCTC2407121006E No.：BCTC/RF-EMC-005 Page: 66 of 70 Edition：B.2 15.
