and prevent damage and deterioration to this instrument. To avoid potential hazards, use
this product as specified.

WARNING

■ Warnings on the Cases and Panels of the Instrument

Operator should not remove any cases or panel for any reasons. If you touch
inside the instrument it could result personal shock or fire hazard. Refrain
from spilling any liquid on or inserting anything flammables or piece of metal
into the ventilation of the instrument. Such actions could cause fire, shock,
malfunction and be an accident hazard while the power is on.

■ Warnings on Power Line

●

Make sure to connect only to the rated power line voltage. Excess
voltage may cause fire.

Confirm the voltage of the commercial power line before connecting the AC power
cord. The power frequency of the power line should be 50/60 Hz.

●

Warning on the Power Cord

Use only the optional power cord that is attached to this instrument. The use of the
power cord other than that attached could cause fire hazard.
If the attached cord is damaged stop using it and contact your local LEADER
agent. Should you use a damaged cord, it could cause a shock or create a fire
hazard. When you pull out the cord be sure to hold it by plug and pull from the

2. SPECIFICATIONS

2.1 Description

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.

2.2 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.

• Applicable to multiformat HDTV

For the SDI signals, HDTV 14 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 outputs

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 tri­level 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 he 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.

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 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 tri­level sync signal is applied.

u MEMORY CARD slot

To insert memory card to store the optional NATURAL PICTURE pattern.
Procure a compact flash memory card recommended by Leader Electronics Corp. Refer to
Section 2.3.4, “Memory Card Slot” for detail.

＊Note: When formatting a CF card, use the FAT system; the LT 443D cannot recognize the

CF card formatted in FAT32 system.
To format the CF card of 32 MB or larger capacity on Windows XP, select FAT from
the default (FAT32 file system selected) for formatting.

Notes on using CF memory card:

• A “Vcc = 5 V” type memory card cannot be used.

• Insert the memory card until it in place. If the card cannot be inserted properly, check the
card for up side down. Do not insert the card forcibly. It may cause trouble.

• Do not remove the card while writing or recalling data.

• Do not turn power off while writing or recalling data.

You can store up to three presets of the panel key settings to in the internal memory

(INT_MEM) and up to nine presets to a Compact Flash card (EXT_CARD) ＊1, ＊2.

There are two methods to recall presets: One method in which the settings of all slots are
recalled at once (ALL mode) and another method in which the settings are recalled on

each slot individually (UNIT mode). ＊3
＊1 The compact flash card is not included in the package. The memory card can be

shared with Option 70 (color still picture memory).

＊2 The INT_MEM preset function is supported on firmware version 1.8 or later.
