LEADER LT448

Multiformat Pattern Generator

Feature
  • Applicable to multiformat

    The 17 formats of component signals are provided for DTV conforming to ISDB, ATSC, and DVB standards based on 1920 1080, 1280 720, 720 480, and 720 576 formats. The NTSC/PAL/SECAM composite output and VGA, used for a computer monitor, are provided. These 29 formats are suitable for production line applications of projectors, etc.

  • G, B, R/ Y, PB, PR signal output

    Two component signal formats (i.e., G, B, R/Y, PB, PR) can be selected

  • Sync signal output

    CS (tri-level or binary level), HD, and VD sync signals are output.

  • Monoscope pattern

    Monoscope pattern (i.e., 16:9 for HDTV, 4:3 for SDTV interlace, 16:9(S) for SDTV progressive) suitable for inspecting resolution is provided as standard for the format applicable to DTV.

  • S connector

    Since an S connector is provided to output Y/C separation signals, this instrument is suitable for adjusting and inspecting an equipment with S connector. The S connector identifies S1 and S2 signals.

  • D connector

    The D5 output conforming to JEITA CP-4120 standards is provided as standard.

  • Preset/recall function

    Up to 100 setting conditions of formats and patterns can be stored.

  • RS232C interface

    This instrument can be remotely controlled by using a personal computer.

  • Remote controlling address

    The address to be recalled can be incremented or decremented by grounding the remote connector pin.

  • Signal generator in a digital technology

    The digital signal generator produces highly stable and accurate signals (except audio signals).

  • DVI connector

    DVI-D connector conforming to DDWG standards is provided as standard.

  • NATURAL PICTURE pattern is optionally equipped as factory option.
Applications
The LT 448 Multiformat Pattern Generator is designed to output analog component and composite signals applicable to the DTV systems.

The test patterns generated are monoscope, color bar, crosshatch, gray scale, circle, character, and much more.
