DVC240XR DVR240XR DVB Modulator Demodulator Card
This product has been designated end of life by the manufacturer. Please contact us for info on a suitable replacement.
The Comtech Radyne DVC240XR offers DVB-S2 and up to 32APSK modulation and features a DVC240XR demodulator card which provides support for up to Q/8/16-PSK.
The DVC240XR is a full featured DVB-S2, DVB-DSNG and DVB-S modulator offered as a circuit card assembly (CCA). It runs at data rates from 1 to 238 Mbps and is capable of CCM, VCM and ACM operation. Selections are available for both 70/140 MHz and L-Band operation with a separate monitor port. The unit is intended for integration into a customer provided chassis for DSNG, enterprise and interactive services. The .08” x 10” x 12” (254 x 305 x 20 mm) card easily fits into a 1RU chassis and consumes less than 30 Watts. Integrators and encoder manufacturers find the DVC240XR ideal for applications where a CCA best suits their needs. It permits simple integration of a modulator into a chassis or combining an encoder and modulator into a single unit.
