LT 443D

The LT 443D Signal Generator can be flexibly used for the mul­tiformat digital broadcast systems. Various plug-in units enable
the output of SDI signals (i.e., HDTV, SDTV), sync signals, and
analog signals. By using these signals and genlock functions,
users can customize this signal generator as desired.

FEATURES

•

Plug-in units provide various functions

Since up to four plug-in units can be installed in the main­frame (consisting of a power supply, main signal generator,
and controller), users can customize this signal generator as
desired.
*1 The plug-in unit is installed at the factory; user cannnot

replace the unit.

•

Applicable to multiformat HDTV

For the SDI signals, 14 HDTV format unit and 525 line/625
line SDTV unit are provided. The NTSC/PAL analog video
signal unit is also available.
Since each unit can output the signal simultaneously, a mul­tiformat system can be constructed to satisfy user's require­ments.

•

Various sync output

Two units can simultaneously output HD signals with 74.25
MHz clock and 74.25/1.001 MHz clock.

•

Easy-to-use sync signals

For today's modern age of digital TV systems, BB signal (for
NTSC/PAL) and HDTV tri-level sync signals can be generat­ed from the Analog BB Unit.

•

Ethernet provided

Since the ethernet capability is provided as standard. This
feature can remotely control various functions and monitor
the genlock status.

•

User-friendly operability

Leader's traditional design and operability concepts are
also reflected in this instrument. User-friendly operation
includes significantly reduced power-on initialization time is
advantageous to a high-performance instrument.

OPTION

LT 443D-70 (NATURAL Picture Memory: Option 70)

This option adds the NATURAL picture pattern output
capability to the LT 443D mainframe.
A compact flash memory card is used as an additional
memory to store the NATURAL picture pattern.

Various plug-in units expand the capability of
the Multiformat Signal Generator.

LT 443D-GLA GENLOCK UNIT

2

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 tri­level 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, 10-field black
burst signal with ID 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.

The LT 443D-HD HD-SDI Unit adds the 14 format HD­SDI signal output capability to the LT 443D mainframe.
Various functions (e.g., ID character, simple motion
pictures, embedded audio, NATURAL picture pattern*)
are provided.
*The NATURAL picture function is only usable when
the LT 443D-70 Option is installed in the mainframe.
