WaveCom's MA4050B QAM Modulator Card is part of WaveCom's expanding line of digital CATV products. It is a versatile, commercial quality IF modulator for cable, MMDS, and LMDS applications.

The MA4050B is a modular circuit card designed for use with the WaveCom MA4000 Series. Each MA4000 card chassis with common MA4011B power/control module can contain up to 10 independent MA4050B QAM modulators in a 4U rack mount configuration. In addition to front panel control, each MA4000 chassis is also fully remote controllable via a serial interface or SNMP module.

Utilizing the latest all-digital modulation techniques, the MA4050B QAM modulator card can be configured to produce QPSK, 16, 32, 64, 128, or 256 QAM. The data may be coded to comply with DVB, DAVIC, or Digicipher II & trade standards. The MA4050B QAM modulator card is available with a number of data interface standard features, including DVB parallel, DVB synchronous serial, and DVB asynchronous serial interface (ASI coaxial). The MA4050B QAM modulator card is capable of automatically synchronizing to the MPEG sync byte at appropriate intervals. This advanced, cost-effective QAM modulator offers high performance, flexibility, and space efficiency.
