Checks the Transmission Margin of the Coaxial Cable Laid in a HD-SDI/SD-SDI(525) System

GENERAL

The LT 9610 is a handy tool for checking the transmission margin of the coaxial cable laid in a HD-SDI/SD-SDI system. The HD-SDI/SD-SDI signal source and the HD-SDI/SD-SDI equivalent cable length display are built in. It converts the level of transmission attenuation of the coaxial cable under measurement to a cable length of a given cable type and displays the result.

FEATURES

  • Supports HD-SDI (1080i/59.94 1.485 Gbps) and SD-SDI (525i/59.94 270 Mbps).
  • By converting the amount of transmission attenuation of the coaxial cable to a cable length of a given cable type, the following points are featured.
    • The amount of transmission attenuation is intuitive as compared to displays such as the power value.
    • If the characteristics of the cable are degraded due to the cable wearing out, the length is indicated longer than the physical length. This enables the amount of degradation and transmission performance to be determined.
    • In a system in where different types of cables are used, the performance of the system (system margin) can easily be determined, because the cable length is displayed in terms of a given cable type.
  • Built-in Signal Generator
    • Because the HD-SDI/SD-SDI signal generator is built in, there is no need to prepare a separate signal source. In addition, highly accurate measurement is possible, because the signal generator and the equivalent cable length meter can be calibrated as a single instrument.
    • The test pattern of the signal generator can be set to color bar or check field pattern. This enables the LV 7700 to be used as a simple standalone HD-SDI/SD-SDI signal generator.
    • Up to 20 ID characters can be multiplexed in the test pattern of the signal generator.
    • 8 channels (4 channels × 2 groups) of embedded audio can be embedded.
  • GO/NO GO Judgment
    By setting a threshold value against the cable length, GO/NO GO judgement can be carried out with ease.
  • Built-in Error Monitor Function
    Equipped with an SDI transmission error monitor function for TRS errors, CRC errors, etc.
  • Battery Operation
    Designed to operate with AAA nickel hydride batteries placing emphasis on portability. In addition, rechargeable batteries that are commercially sold can be used.
  • Compact and Light
    Hammer head type that can be held single-handedly.
