oscillators are self-calibrating and can be disciplined to a 1PPS input reference for maximum
accuracy.
To determine which oscillator is installed in your SecureSync unit, navigate to MANAGEMENT
> OTHER: Disciplining. The first entry in the Status panel on the left indicates the type of oscil-
lator:
Because of its high degree of stability, the Rubidium oscillator provides the greatest ability to
extend the hold-over period when input references are not present. Extending the hold-over
period allows the unit to provide very accurate and useable time stamps and a 10 MHz output
for a longer period of time once time synchronization has been lost.
Note: Oscillators are installed at the factory, in accordance with order spe-
cifications; an oscillator cannot be swapped/retrofitted later in the product life
cycle (with the exception of repairs).
The Rubidium oscillator is atomic in nature but requires no MSDS (Material Safety Data Sheet).
For additional information on oscillator accuracies, see "10 MHz Output" on page25.
Note: External Oscillator: It is possible for an external oscillator to be locked to
SecureSync's 10MHz output via an external PLL, with the lock state of the
external PLL monitored by SecureSync. Contact Spectracom for more information.
3.5.2 Configuring the Oscillator
SecureSync is equipped with an internal oscillator. To configure the oscillator settings:
1.
Navigate to MANAGEMENT > OTHER: Disciplining.
2.
Click the GEAR icon at the top of the Status panel. The Oscillators Settings window will dis-
play:
