7.2 Setting GENLOCK Mode
The GENLOCK MODE SET is used to select the genlock mode.
● Description of Setting Items
INTERNAL The internal reference signal is used. Select this item
when no need to lock the instrument to the external
signal. (initial setting)
AUTO (GO INTERNAL) The EXT mode is automatically selected when the
external reference signal is applied to the GENLOCK
input. The INT mode is automatically selected when the
external reference signal is removed.
The instrument is automatically genlocked to such
signals as HD tri-level sync signal, NTSC, and PAL.
When the external reference signal is used to lock the
instrument, select this mode to immediately lock the
instrument to the external reference signal even when
ignoring any abnormal picture momentarily is displayed
due to a transient in lock operation.
MANUAL (GO INTERNAL) The instrument locks to the signal being set according
to the GENLOCK FORMAT selected. The EXT mode is
automatically selected when the external reference
signal with the same format specified to the GENLOCK
input is applied after the power is turned on.
The INT mode is automatically selected when no
external reference signal is applied to the GENLOCK
input, or signal format not match to the specified format
is applied. When the external reference signal is used
to lock the instrument, select this mode to immediately
lock this instrument to the external reference signal
even when ignoring any abnormal picture momentarily
is displayed due to a transient in lock operation.
AUTO (STAYinSYNC) The EXT mode is automatically selected when the
external reference signal is applied to the GENLOCK
input after the power is turned on. If the external
reference signal is accidentally intermitted during
operation, the STAYinSYNC function retains the
conditions immediately before trouble occurs to
continue the operation. The EXT LED blinks in this case.
After the external signal is recovered, the instrument
automatically goes into lock status. It may take a time
until the instrument locks. The transient may occur
when locking the system.
