KR2401 DVBT Modulator with ASI in

Overview

The KR2401 DVB-T Modulator is a high performance modulator
developed according to DVB-T (EN300744) standards
It incorporates advanced framing structure, channel coding
and modulation technology
It also supports both MFN (Multi-frequency network)
and and SFN (single frequency network) configurations
It has 2 ASI input ports, one GPS 10MHZ input port
and one 1 PPS input port
In order to improve the output performance of the transmitter
the DVB-T modulator can simultaneously support linear
and nonlinear pre-correction
This device supports local and remote control through NMS software

If this unit is not in stock it will take 30 days to procure
