Standard
Masterclock oers 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.
