Comtech DMR240XR Digital Video Broadcast Modulator
The DM240XR is DVB-S2 ready and can easily be upgraded in the field. The DM240XR provides a comprehensive set of advanced S2 features. The DM240XR extends its dominance in broadcast applications through increased data rate capability and the addition of 16-APSK and 32-APSK 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 DM240XR includes the ability to select the output frequency of 70/140 MHz or L-Band operation without any hardware modifications. The DM240XR offers high data rates and flexible modulation schemes.
The DM240XR AutoEQ feature supports Amplitude and Group Delay equalization over the satellite system. When installed, AutoEQ offers the ability to compensate the overall system Group Delay and Amplitude Flatness by pre-correcting the Uplink Carrier. This eliminates the need for external Group Delay/Amplitude Equalizers.
The DM240XR also offers the flexibility to support up to three different data interfaces
