La description

ISDB-T/Tb BTS Modulator is developed to adapt Japan, Brazil, Argentina and other South American countrys terrestrial
digital television, the modulator's channel coding and modulation mode is fully complying with the ARIB STD-B*1 standard.
This ISDB-T/Tb BTS modulator supports four TS hot backup , single frequency network and multi-frequency network,
linear and nonlinear pre-correction function, layered transmission and the three transmission modes mentioned in the
standard. Furthermore, this device can be upgraded and controlled through network system, which can be widely used in
ISDB-T/Tb digital broadcasting network's setting up and set-top box design's production and test.

Features
    Fully complying with ISDB-T (ARIB STD-B*1) and ISDB-TB standard
    Single frequency SFN and multi-frequency MFN network
    Layered transmission with A, A+B, A+B+C hierarchy modes
    DVB TS (without IIP packet), TS multiplexing, re-multiplexing and multiplexed frame generating;
    ISDB-T BTS (with IIP packet), IIP packet parsing and multiplexed frame generating
    Three transmission modes: mode1(2k), mode2(4k), mode3(8k)
    Liner and nonlinear pre-correction function
    MER≥*2db
    RF output range: *0~**0MHz in 1Hz step
    4 channel ASI , hot backup
   Constant temperature crystal and excellent frequency stability
    2 ASI s with loop out and hot-backup online
    Constant temperature crystal oscillating and excellent frequency stability(reach up to 0.1ppm)
    LCD display, keyboard and NMS operation
