SOUTHERN AVIONICS COMPANY 2 Theory of Operation, Radiobeacon 2.1 Functional Description: SA100 Synthesizer: The RF signal is generated on the KWOSYN PWB by a voltage controlled LC oscillator operating at twice the RF frequency. This signal is divided to produce a 1 KHz signal that is fed to a phase locked loop (PLL) and compared with a 1 KHz signal produced by a divided 4.096 MHz crystal oscillator signal.
Page 32 AC and DC supplies, the optional batteries supply power without interruption whenever AC power is lost. Battery Charger (optional): The optional battery charger system automatically charges the batteries in two modes, fast charge and float mode depending on the battery condition.
