Limits 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. 8.3. Test procedure (1) The test according to ANSI C63.10-2013 clause 7.8.4. (2) Connect EUT’s antenna output to spectrum analyzer by RF cable, the path loss was compensated to the results. (3) Set the EUT as maximum power setting and enable the EUT transmit continuously. (4) Use the following spectrum analyzer settings for the maximum peak output power measurement: RBW: ≤ channel spacing and where possible RBW should be set >>1 / T VBW: VBW ≥ RBW. Span: Zero span, centered on a hopping channel. Detector Mode: Peak Sweep time: Auto Trace mode: Clear Write. (6) Measure and record the results in the report. (5) The test period: T= 0.4 Second/Channel x 79 Channel = 31.6 s (6) Measure the hopping number and on time of each pulse with spectrum analyzer in zero span set, and calculate dwell time with formula Dwell time = total hops *pulse’s on time. (7) ppendix E: Time of occupancy Guangdong Dongdian Testing Service Co., Ltd. Report No.:DDT-RE23070308-2E01 TRF No.: FCC Part 15C BT Ver.1.0 Page 29 of 91 8.4.
