Adjustments For Genlock Operation - JVC RM-HP250DE Instructions Manual

Adjustments for Genlock Operation

Genlocking is required for a system, which uses an SEG (special effects generator) as the main
signal source.
REF. : "Example of Connection with 2 Units" on page 9.
NOTE
The following adjustments can be made more accurately when using a vectorscope and waveform monitor.
Be sure to use an underscanned video monitor.
It is not permitted to genlock the system components using a VCR playback signal.
Before phase adjustment, wait a little for the phases of the connected components to stabilize.

When the upper or lower limit of SC FINE is exceeded,
the value of SC COARSE changes.
For example, when the value of SC COARSE is 0° and
SC FINE is increased, once SC FINE exceeds 127, SC
COARSE will become 90° and SC FINE will become -
128.
