If the signal is not valid, the indicator will be orange. A clean up oscillator may be inst A three-position front panel switch chooses automatic operation or may be used to manually select one of the two input sources.

Applications Radio Base Stations: But, this is the same issue studied in Section A word linr the day is a transmission security variable that consists of six segments of six digits each.

An absolute timing accuracy of better than Certain haveqjick of these standards can interoperate. Timscode include a precision time code that might be a useful source to discipline a computer clock, such as might be found on an air force aircraft or navy vessel.


The GPS8 is a staple of Brandywine being a reliable, low cost Time and Frequency instrument offering a wide range of standard features in a compact, 1U rack-mount chassis.

Progress in electronics in the s reached a point where anyone with an inexpensive radio frequency scanner or receiver set could intercept military communications.

This page was last edited on 22 Decemberat The Status window displays the following settings: The modern military battlefield and infrastructure support have become extraordinarily dependent on precise time and frequency distribution for radio communication and long-haul fiber and satellite communication systems.

The available choices are: Time synchronization can be achieved by simply reading the time registers, using the SYNCCLOCK card to generate periodic interrupts, or latch the time of an external event.

The M is a Modular Timing System provides a Master Clock based upon a central microprocessor and a precision oscillator time base for many applications including synchronizing comput By using this site, you agree to the Terms of Use and Privacy Policy. For enhanced phase noise performance an optional clean up oscillator is installed between the rear panel inputs and the inputs of the transfer switch.

At intervals something less than 1 s, the NIC driver updates the structure holding the last NIC clock and system clock and trims the K multiplier.


The Have Quick II format appends the day of the year in three octets followed by the year in two octets.

The FDUi is a high performance signal distribution amplifier designed for use with Brandywine high precision time and frequency sources.
