The Tempest Parallel Sync Generator produces a sync signal that aligns the hop sequence as well as the transmit cycles of the connected Base Stations. Sync is output on 12 isolated ports. There is also a Sync In port so that boxes can be daisy-chained. The beginning of a hop sequence is indicated with a short pulse (1% duty cycle). The remaining 5804 pulses in the sequence use a 50% duty cycle.
