The modem is DVB-S and DVB-S2 capable with the ability to upgrade from DVB-S to DVB-S2 in the field. The DM240XR extends its dominance in broadcast applications through increased data rate capability and the addition of 16APSK and 32APSK support. DVB-S2 performance operating near Shannon’s limit offers results with 30% better bandwidth efficiencies (compared with DVB-S) and carrier to noise figures below the noise floor.

Our next generation integrated IP demodulators provide industry-leading performance in a 1 RU package at a competitive price. They are designed to receive up to four independent 70/140 MHz or L-Band channels (depending on model) and combine the receive data into a single 10/100Base-T Ethernet port for transmission onto the LAN. The demodulators are designed to operate with Comtech EF Data’s CDM-570/L-IP and CDM-570A/L-IP IP-enabled modems. The CDD-564A/LEN & CDD-562ALEN models feature 3xDES encryption.
