master frequency generator
In frequency-division multiplexing (FDM), equipment used to provide system end-to-end carrier frequency synchronization and frequency accuracy of tones.
Note: The following types of oscillators are used in the Defense Communications System FDM systems:Type 1 – A master carrier oscillator as an integral part of the multiplexer set.
Type 2 – A submaster oscillator equipment or slave oscillator equipment as an integral part of the multiplexer set.
Type 3 – An external master oscillator equipment that has extremely accurate and stable characteristics. Synonym master oscillator.
