Spectracom SecureSync 1200 - 5.2.3.6 Programmable Square Wave Out [1204-17]

Signature Control: Controls when the output will be present. See also: "Signature Con
trol" on page136.
Frequency: Indicates the configured frequency.
Phase: Displays the configured phase offset (e.g., to account for delays caused by dif
ferent cable lengths, or other latencies).
Lock: Shows, if the output frequency is locked to the SecureSync system-disciplined oscil
lator.
Note: Even if an output frequency status is LOCKED, it will not be available at the
output port, if the Signature Control for that port has been DISABLED.
