Orolia SecureSync 2400 User Manual

SecureSync equipped with TCXO/OCXO/Low-Phase-Noise Rubidium oscil-
lator: With oscillator disciplining active (one or more 1PPS references available and
valid) and after the on-time point has been initially slewed into alignment with the
selected reference, there will always be exactly 10million counts of the oscillator
between each 1PPS output, even while in the Holdover mode (= input references
are currently unavailable) and even after input references have become available
again.
SecureSync equipped with Rubidium (Rb) oscillator: With oscillator disciplining
active (one or more 1PPS references available and valid), after the on-time point has
been slewed into alignment with the selected reference, with the exception of 1PPS
input reference changes occurring, there will always be exactly 10million oscillator
counts between each PPS output pulse.
With the Rubidium oscillator installed, when a 1PPS input reference change occurs
(such as switching from IRIG input to GNSS input, or switching from a reference
being valid to no reference being present or valid—known as the Holdover mode),
the oscillator counts between two 1PPS outputs may momentarily not be exactly
10million counts. Once the reference transition has occurred, however, the counts
between each PPS output pulse will return to exactly 10million counts.
Like other types of SecureSync's signal outputs, a 1PPS output can be configured in sev-
eral ways:
Signature Control allows you to determine under which conditions an output sig-
nal shall be present, i.e. what SecureSync will do about a given output when an
external reference is lost. See also "Signature Control" on the facing page.
The on-time point of the 1PPS signal: rising or falling edge
The pulse width
An offset can be entered to account for cable delays or other latencies.
2.21 The Option Cards Screen
This menu lists all the interfaces on the unit, including the option cards installed on your
SecureSync.
The rear panel connectors included with a standard SecureSync are all listed in this menu
under "Main" and "Option Card 0".
