Model/Varenr.: DX-EC2401C
The Eurocaster EC2401C DVB-T Modulator is a high performance modulator developed according to 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). It equipped with four ASI hot backup input, one GPS 10MHz input port and one 1PPS input port. In order to improve the output performance of the transmitter, this DVB-T modulator also simultaneously supports adaptive linear and nonlinear digital pre-distortion. Moreover, this device facilitates the local and remote control with SNMP software.
