The LT 4610 is 1RU full-rack size sync signal generator that can output triple-rate SDI (3G-SDI/HD-SDI/SD-SDI) signals. It employs two power supply units for redundant operation to protect against power supply failures. The genlock function for external sync signals enables SDI signals, six sets of analog black burst sync signals, and audio word-clock signals to be output synchronously. The genlock function is equipped with a STAY IN SYNC function that maintains the phase when errors occur in the input signal, making it possible to provide stable sync systems.
In addition to test pattern output including color bars and SDI check fields, the LT 4610 can embed ID characters, QVGA logo marks, safety area markers, and embedded audio in a SDI signal output.

Features

  • Triple-rate SDI Ready
    SDI signal output supports 3G-SDI (level A and level B), HD-SDI (including dual link), and SD-SDI. There are two independent outputs of SDI signal outputs. The pattern and phase can be set separately for each. (However, only a single output is available for 3G-SDI level B and HD dual link.)
  • ID Character Overlay
    ID characters can be overlaid at any position on the display. In addition, ID characters can be scrolled horizontally or displayed in a blinking state for checking whether the display has frozen.
  • Logo Mark Overlay
    A logo mark converted from bitmap can be overlaid at any position on the display at a standard 320 (dot) × 240 (line) size (QVGA size).
  • Safety Area Markers
    90% and 80% safety area markers can be overlaid on the display. For 3G-SDI and HD-SDI, a 4:3 aspect marker can be overlaid.
  • Pattern Scrolling
    Equipped with a function for scrolling patterns in eight directions. The speed can also be adjusted.
  • Audio Embedding
    The LT 4610 can embed 32 channels (link A, link B, 4 channels each × 4 groups) of audio signals for 3G-SDI level B and 16 channels (4 channels × 4 groups) of audio signals for 3G-SDI level A, HD-SDI, and SD-HDI. The frequency and level can be set for each channel.
  • Lip Sync Patterns (3G-SDI level A, HD-SDI, SD-SDI only)
    The LT 4610 can output lip sync patterns in which the video and audio are synchronized. When combined with a waveform monitor that features a lip sync function, such as the Leader LV 5770A, it is possible to accurately measure the offset between the video and audio in SDI signal transmissions.
  • Genlock Function
    The LT 4610 can be synchronized with NTSC/PAL black burst signals and HDTV tri-level sync signals. NTSC/PAL black burst signals with a field reference pulse and NTSC black burst signals with 10 field IDs are also supported. A STAY IN SYNC function is available in case errors occur at the genlock input. The LT 4610 also has a slow lock function to reduce the shock that occurs when genlock is performed again based on STAY IN SYNC.
  • Analog Black Sync Signal Output
    The LT 4610 is equipped with six independent analog black burst sync outputs, which can also be HDTV tri-level sync outputs and can be individually timed. NTSC/PAL black burst signal with field reference pulse and NTSC black burst signal with 10 field IDs are also supported.
  • Word-Clock Signal Output
    The LT 4610 can output a 48 kHz word-clock signal synchronized with the video signals.
  • AES/EBU Signal Output
    The LT 4610 can output a 48 kHz AES/EBU signal synchronized with the video signals. It is also equipped with a muted AES/EBU signal output.
  • Real Time Clock
    The LT 4610 can output a 48 kHz word-clock signal synchronized with the video signals.
  • Ethernet
    SNMP is supported as standard. When an error is detected, a TRAP is issued.
  • Preset Memory Function
    Up to 10 preset memories can be saved. Conveniently saved presets can be recalled during operation. The LT 4610 can be started with the same settings every time.
  • External Memory Support
    Logo data and preset data can be written and saved from the front panel using USB memory devices.
  • Redundant Power Supply
    Two power supplies are built in to provide redundancy. When errors occur in power supply units, alarms are indicated on the LT 4610 panel. Errors can also be output as alarms using SNMP.
  • LT 4610SER01 GPS Option
    This option adds (1) a GPS lock function, which locks to the frequency and time that can be obtained from GPS, (2) a 10 MHz CW lock function, and (3) time code generator function.
  • LT 4610SER02 12G-SDI Option
    The LT 4610SER02 12G-SDI Option adds four SDI signal outputs and support for 12G-SDI.
    The SDI signal outputs support 4K 12G-SDI, 4K 3G-SDI quad, 4K HD SDI quad, 4K 3G dual, 3G-SDI (level A and level B), HD-SDI (including dual link), and SD-SDI. Four SDI signal output connectors are available. The format must be the same for all four outputs, but the user can set different patterns and phases for each.
    (However, only two outputs are available for 3G-SDI level B and HD dual link.)
