3.5.5. Synchronizing The System Master Oscillator to the Frequency Reference Immediately
INPUT
JAM SYSTEM NOW
Force System Jam
Reset Genlock
This menu item allows the user to synchronize the master system oscillator
to its frequency reference. This will only be necessary when the
Lock
Control
menu item is set to slow and there has been an abrupt change in
the freqeuncy reference (e.g. a sudden change of video phase when the
Frequency Reference menu item is set to Video ref)
To synchronize all the system master oscillator to the Frequency reference
immediately, press the
SELECT button when Force system jam is
shown on the display. The front panel display will show
SYSTEM JAMMED
for 0.6 seconds after the oscillator has been synchronized.
The internal frequency reference oscillator in the 5600MSC is calibrated at
the factory to that it can quickly stabilize when power is applied to the unit.
These frequency control parameters are saved in the non-volatile memory
of the 5600MSC. To recalibrate the frequency locking system of the
5600MSC press the
SELECT button when Reset Genlock is shown on
the display. You will be prompted to make sure this is what you want to do.
Recalibration may take up to 30 seconds. This must only be done when the
reference is known to be stable and accurate.
"
Re-synchronizing the master oscillator or Resetting the genlock may disrupt the
timing of all the sync outputs, and the LTC and VITC timecodes and therefore must
be used with caution.
