OPERATION
3.5.6. Configuring the Lock Speed
INPUT
LOCK CONTROL
Abrupt lock
Slow lock
The
LOCK CONTROL
menu item is used to select whether the 5600MSC
will abruptly lock to its frequency reference or slowly rephase until it
achieves a locked condition when the
GENLOCK RANGE
menu item is set
to
GL range narrow
.
When set to
Abrupt lock
the 5600MSC will make a sudden change in
internal oscillator to bring it into lock with the time and frequency reference
being applied. This setting may cause disturbances to the sync and
timecode outputs as the unit relocks to its reference.
When set to
Slow lock
the 5600MSC will gradually adjust its internal
oscillator to bring it into lock with the time and frequency reference being
applied. This setting will not cause any disturbances to the sync outputs as
they rephase. If the 5600MSC detects a change in its frequency reference
that is outside its frequency capture range then it will not be able to slowly
rephase to the new frequency. In this case a
System Jam
will be required in
order for the 5600MSC to relock to the reference. (See section 3.3.3 and
3.5.5.)
When the
GENLOCK RANGE
menu item is set to
GL range wide
the
LOCK
CONTROL
menu item will be set to
Abrupt lock
and the front panel display
will be dimmed to indicate that you can not change this menu item.
