This unit provides genlock capability to lock the LT 443D mainframe with the external reference signal, and three independent black signal generators.
The NTSC/PAL black burst signals, Principal 20 types of HDTV analog tri-level sync signal formats, and 525p/625p analog sync signals can be used as an external reference signal.
The following black burst signal formats can be selected.
For NTSC/PAL system, black burst signal with field reference pulse is provided. For NTSC system, black burst with 10-field sequence identification conforming to the SMPTE 318M standards is provided.
The instrument continues operation since the flywheel mode is provided even if the external reference signal is accidentally removed in genlock mode. By logging the genlock status, the time can be obtained when the external reference signal is removed. The log information can be stored on the CF CARD.
The genlock timing can be adjusted for the entire color frame range when the NTSC/PAL black burst signal is applied; entire frame range when the HDTV analog tri-level sync signal is applied.
Three black burst signal output systems with selectable formats are available as follows:
For NTSC/PAL system, standard black burst signal and black burst signal with field reference pulse are provided. For NTSC system, black burst signal with 10-field sequence identification conforming to the SMPTE 318M standards, 525p/625p analog sync signal, and HDTV analog tri-level sync signal are provided.
The format and output signal timing of each output can be respectively set. The black signal timing can be adjusted for the entire color frame range when the NTSC/PAL black burst signal is applied; entire frame range when the HDTV analog tri-level sync signal is applied.
