Standard

        Masterclock offers three high-stability oscillator options for the GMR Series. When locked to GPS, the OCXO 10 MHz sine wave frequency 

will have the same long-term stability as an atomic clock. When not tied to GPS, a precision frequency 10 MHz reference output is 

        available as a source for laboratory use or for an RF reference, including cellular applications. The HSO option is required for all 
        10 MHz signal outputs.
