The Comtech Radyne DM240XR DVB-S2 32APSK DSNG Broadcast Modulator offers an extremely adaptable broadcast modulator platform that’s capable of DVB or DVB-S2 and 70/140 Mhz IF or L-Band operation. The Comtech Radyne DM240XR DVB-S2 32APSK DSNG Broadcast Modulator offers a great AutoEQ feature that 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 precorrecting the Uplink Carrier. This eliminates the need for external Group Delay/Amplitude Equalizers and makes possible equalization at L-Band. The AutoEQ will operate over the full transponder from a symbol rate of 10.1 Msps to 45 Msps.
