Parallel Zero Sync Generator (SG-120)
The Tempest Parallel Zero Sync Generator (PSG) provides a precise, zero
reference synchronizaon signal to each connected Tempest 2.4GHz
BaseStaon. This signal aligns the hopping paerns and transmit/receive
mes of all connected BaseStaons to produce the best possible mul-
base, collocated RF performance.
A single Tempest Parallel Zero Sync Generator supports up to 12 Tempest
2.4GHz BaseStaons using the 12 isolated Sync Out DE-9 connectors
on the rear panel of the PSG. Each BaseStaon is connected directly
to the Parallel Zero Sync Generator via a DE-9 extension cable in a star
conguraon. The connecon is made from a PSG Sync Out DE-9F to each
BaseStaon’s Base Sync In DE-9M connector. This allows each BaseStaon
to receive the proper synchronizaon signal completely independent of
the condion or presence of any of the other BaseStaons.
If more than 12 Tempest 2.4GHz BaseStaons are required, a second Parallel Zero Sync Generator may be added. In this
case the two PSGs must be connected together ulizing the Sync Out DE-9F connector on the rst PSG to a Sync In DE-9M
on the rear panel of the second PSG. This will allow the synchronizaon of up to 23 Tempest 2.4GHz BaseStaons.
