The Status window displays the following settings:
Signature Control: Controls when the output will be present. See also: "Sig-
nature Control" on page183.
Frequency: Indicates the configured frequency.
Phase: Displays the configured phase offset (e.g., to account for delays
caused by different cable lengths, or other latencies).
Lock: Shows, if the output frequency is locked to the SecureSync system-
disciplined oscillator.
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.
