Other configurations are possible. The Dual Master Oscillator will contain a GPS clock, a Rubidium oscillator, timing distribution, and switching. Various combinations of the required functions are available commercially and a product search is required to finalize the design. 714MHz nominal, External time base from master source. Provides a tap for master oscillator diagnostics.
Transmitter is configured for electrical RF input with fiducial.
This unit takes the 60Hz power line, and backplane commands to generate a fiducial pulse. The fiducial pulse is sent to the stable fiber optics transmitter. Fibers will take the signal from each of the Stable Fiber Optic Transmitters to each sector. Two VXI crates to provide fanout to additional timing systems. The additional slots in the crate are avaialble for general use.
