Overview
The NDS2401G DVB-T Modulator is a high performance modulator developed according to the DVB-T (EN300744) standard. It adopts advanced framing structure, channel encoding and modulation technology. It supports both MFN (Multi-frequency network) and SFN (single frequency network). In order to improve the output performance of the transmitter, this DVB-T modulator can support nonlinear digital pre-distortion. Moreover, this device facilitates the local and remote control with web software. 9. Supports adaptive non-linear digital pre-distortion (DPD) Key Features: 1. Fully complying with DVB-T standard (EN300744); 2. 2 ASI in & 2 IP (DATA1& DATA2) input for hot backup input, 1 RF in, 10MHz reference; clock and 1PPS in; 3. Support both SFN and MFN; 4. Transmission mode: 2k, 8k; 5. Transmission bandwidth 5M, 6M, 7M and 8M; 6. Excellent phase noise and MER performance, MER≥42db; 7. Support spectrum invert; 8. RF output range 50~1000MHz, 1Hz step; 9. Supports adaptive non-linear digital pre-distortion (DPD); 10. Constant temperature crystal oscillator, frequency stability is high up to 0.1ppm
