NDS2405C ISDB-T modulator is developed to adapt Japan, Brazil, Argentina and other South American country’s terrestrial digital television. The modulator's channel encoding and modulation mode is fully complying with the ARIB STD-B31 standard. This ISDB-T modulator supports four ASI hot backup input, single frequency network, and multi-frequency network. In order to improve the output performance of the transmitter, this ISDB-T modulator also simultaneously supports adaptive linear and nonlinear digital pre-distortion, layered transmission and three transmission modes. Furthermore, this device can be upgraded and controlled through network system, which can be widely used in ISDB-T digital broadcasting network's setting up and set-top box design's production and test.Features:- Fully complying with ISDB-T (ARIB STD-B31) and ISDB-TB standard- 4 ASI in, 1 RF in, 10MHz reference clock and 1PPS in- Layered transmission with A, A+B, A+B+C hierarchy modes- ISDB-T BTS input (with IIP packet), support single frequency and multi frequency network- Three transmission modes: Mode1(2k), Mode2(4k), Mode3(8k)- Supports adaptive linear digital pre-distortion (DPD)- Supports adaptive non-linear digital pre-distortion (DPD)- MER bigger or equal 42db- RF output range: 30-960MHz with 1Hz step- Constant temperature crystal oscillating and excellent frequency stability (reach up to 0.1ppm)- LCD display, keyboard and SNMP software operation
