LEADER Info

LEADER INSTRUMENTS

Since its beginning 50 years ago, Leader has earned a worldwide reputation for designing and manufacturing some of the most reliable, practical and cost effective electronic instruments available. The products were originally developed for production testing and servicing. These are applications in which ease-of-use and highest reliability are essential. By expanding into a broad line of industrial and video instruments, Leader was able to add to these fundamental qualities a cost-performance ratio unequalled in the industry.

Manufacturing quality is built in every step of the way. Only the finest parts are used for optimum reliability. At each production run, sub-assemblies are separately tested before they are integrated into the finished product. Then product is tested. Less than 1% of all Leader products made are ever returned for warranty repair or adjustment.

More and more, Leader products - over 100 of them - are being specified for research, development, production and service applications in addition to over 100 instruments customized for production line applications.

    LT 4440 Changeover

    The LT 4440 is a changeover unit that automatically switches the signal from the primary signal to the backup signal when problems are detected in the primary signal.
    A single LT 4440 provides 11 channels. HD-SDI (channels 1 to 6 only), SD-SDI, AES/EBU digital audio, analog black burst signal, and tri-level sync signals are supported through the configuration of the internal switch.

    Input/Output
    Provides 11 channels (a single channel consists of PRIMARY input, BACKUP
    input, and OUTPUT output) on a single LT 4440.
    Delay for Starting the Monitor
    The delay for starting the error monitor at power up can be set to FAST or
    SLOW depending on the rise time of the system signal source being
    connected.
    Determination Criteria of the Signal Level
    The internal preset switch allows level detection switching among SD-SDI,
    AES/EBU digital audio, NTSC or PAL analog black burst, HD analog tri-level
    sync, HD-SDI (only supported on channels 1 to 6), and other signals.
    Error Display
    When a signal level error is detected, the LT 4440 illuminates the error
    LED on the panel as well as the LED panel that indicates the channel
    causing the problem. This feature allows quick investigation of the problem.

    Rasterizers

    The LV 7330 is connected to an external XGA or WXGA monitor, it can display the picture of an HD-SDI or SD-SDI signal in addition to video signal waveforms, vectors, audio data, and data analyses of the signal. The LV 7330 also comes standard-equipped with CINELITE Ⅱ, a convenient tool for analyzing luminance data.

    lv_7330LV 7330

    lv_7330_2e

    lv_7330_3

    SDI I/O
    The LV 7330 has two SDI input connectors that can be used for both HD-SDI and SD-SDI input. It also has an SDI output connector that you can use to send a reclocked SDI signal.
    DVI Output
    The various LV 7330 displays are transferred through a DVI-I connector to an XGA (1024 × 768) display. The LV 7330 also uses a squeeze method to support aspect ratios of 16:9 (1366 × 768) and 16:10 (1920 × 1200)
    CINELITE Ⅱ
    The LV 7330 comes standard-equipped with CINELITE Ⅱ(CINELITE and CINEZONE), which is a video signal luminance information analysis tool.
    With CINELITE, you can use the cursor to select any 3 points and display their f-Stop numbers, percentage values, and level values. You can choose to analyze a single pixel or a small area by setting the size of the measured area to 1 pixel or to the average value for 9 or 81 pixels.
    With CINEZONE, you can display the luminance levels in the picture using different colors. This allows you to quickly determine the overall luminance distribution in the picture, and it makes it easy to spot overexposure, underexposure, and different luminance levels in dark areas.
    Picture Display
    The LV 7330 has a wide assortment of SDI signal picture display features including zoom, various safety markers, and brightness, contrast, and chroma adjustment. The LV 7330 also supports CEA/EIA-608 closed captioning and superimposition.
    Video Signal Waveform Display
    The LV 7330 uses fully digital waveform display processing to achieve high precision and quality. From video signal waveform display gain expansion, sweep expansion, and cursor measurement to pseudo-composite and RGB displays, the LV 7330 has all of the features that people look for in a waveform monitor. The LV 7330 is equipped with an external sync signal input and it can display video signal waveforms based on a tri-level sync signal or an NTSC or PAL black burst signal.
    Vector Display
    The LV 7330 can display component chrominance signal vectors. The amplitude can be manually zoomed, or set to a fixed magnification value such as five. The IQ axes, which are useful for vector observation, can be turned on and off.
    5 Bar Display
    The LV 7330 can display the peak levels of the Y, R, G, B and pseudo-composite signals.This feature is useful for monitoring gamut errors.
    Audio Display
    The LV 7330 can extract the audio signal embedded in an SDI signal and display level meters, Lissajous curves, and surroundsound images for up to eight channels. The LV 7330 also supports external digital audio input, for which it can display a two-channel level meter and Lissajous curves. The level meter supports loudness metering and is useful for managing the volume level experienced by the listener.
    * The resolution of SD-SDI audio quantization is up to 20 bits.
