Switch 6 – Master/Slave configuration
ON OFF
Switch 6-1 Master (generates and
distributes RF and Sync)
Slave (system must receive
Sync signal)
The Master/Slave switch controls how the system will handle the sync and rf signals in
and out. A system MUST be in slave mode to use these input signals. In Master mode
these signals must be absent (refer to ‘Sync and RF indicators’ section).
ON OFF
Switch 6-2 ‘EVEN’ pedestal ‘ODD’ pedestal
The Even/Odd switch controls the transmit signal phase. This allows for a improved
received signal in the weaker carries. For rf slaved systems this switch is alternately set
even-odd-even-odd ….etc. For compatibility with older Strata systems ‘On’ is the same
as having the Even/Odd link installed.
Switch 7 – Sweep range select
The Strata 99-4022 board introduces the digital synthesis of the sweep frequencies from a DDS
chip. Without any test equipment the system can be setup without tuning for specific sweep
ranges.
