A special "Stay GenLock" mode ensures that no loss of test signal or black outputs occurs with momentary loss of synchronization at the genlock reference input. When the genlock signal is reapplied, the feature gradually reacquires lock to minimize disruption and will not cause noticeable glitches. Genlock source can be NTSC/PAL Black Burst, NTSC/PAL Sync, or CW. When using CW lock, genlock timing can be adjusted on all the NTSC or PAL color frames.
