The SyncServer S600/S650 has separate timing and frequency clock controls.
The squelch feature uses the time clock state for timecode and fixed-rate pulse
modes. The squelch feature uses the frequency clock state for
programmable-period pulse and sine modes.
The time clock state can be viewed on the "Time of Day Status" line on the
Dashboard >Timing display. Normally frequency and clock states are the same. If
they are different, then the frequency clock state is displayed next to the icon on the
"Current Reference" line.
