INTRODUCTIONS
RMA9030 ATSC-T Modulator adopts several advanced functions and technologies, based on its fundamental module. It adopts Linear Digital Pre-Distortion and Non-Linear Digital Pre-Distortion, with which Adjacent Channel Power Ratio(ACPR) is able to be well improved. Fully compliant to standard ATSC A.53, the device supports both ASI and SMPTE-310M inputs, and then modulate them in ATSC 8VSB. It outputs 1* RF signal range 40~960MHz. RMA9030 additionally has 1*GPS 10MHz reference clock input, and its frequency stability reaches to 0.1PPM by configuring constant-temperature crystal oscillator. The device is widely applied to digital broadcasting systems of ATSC-T standard.
