Test procedure (1) Connected the EUT’s antenna port to the Spectrum Analyzer by suitable attenuator, The cable loss and attenuator loss have been put into spectrum analyzer as amplitude offset. set the Spectrum Analyzer as below: Centre Frequency: The centre frequency of the middle hopping channel. Resolution BW: 10 MHz. Video BW: 10 MHz. Span: Zero span. Detector: Peak. Trace Mode: Max Hold. Sweep: Video Trigger (2) When the trace is complete, measure the sending time of 1 burst and the duty cycle of 1 burst cycle. (3) Calculate dwell time follow below formula: Duty cycle= Pulse’s on time / Burst cycle Appendix I: Duty Cycle Dongguan Dongdian Testing Service Co., Ltd.
