The R&S^®SMW200A Vector Signal Generator is the ideal tool for DVB-S2 / DVB-S2X physical layer testing. By means of the R&S^®SMW-K116 option, the R&S^®SMW200A flexibly generates customized DVB-S2 / DVB-S2X signals.

DVB-S2 is the common standard for providing TV program from satellites to millions of homes. The physical parameters of the signals are defined to ideally fit the satellite to ground links. Thus the DVB-S2 modulation scheme is not only used for TV broadcast but also for many other professional satellite data services for enterprises, in-flight entertainment, maritime, military and government applications. With DVB-S2X as the newest version higher order modulation schemes are added to increase the data rate in a given frequency band. The standard TV transmission is in the Ku band and other satellite links using the same physical layer are typically in the Ka band. Both are directly addressed with the microwave frequency options of the R&S^®SMW200A up to 40 GHz.

With the high RF bandwidth of the R&S^®SMW200A, DVB-S2 symbol rates up to 600 Msps can be addressed. Flexible multicarrier generation allows transponder load generation with multiple signals for stress testing a complete satellite frontend with up to 2 GHz of bandwidth by summing up multiple channels.
