Comtech’s DM240XR family of high-speed modulators support both DVB-S and DVB-S2
specifications. The DM240XR can easily be upgraded in the field. The DM240XR unit provides a
comprehensive set of advanced S2 features, and extends its dominance in broadcast
applications through increased data rate capability and the addition of 16APSK and 32APSK
support. Proven performance operating near Shannon's limit offers results with 30% better
bandwidth efficiencies and carrier to noise figures below the noise floor.
The plug-in supports three types of alarms: Health alarms, Text alarms, or Bitfield alarms, as
follows:
Health monitoring and text alarms
