R&S®SFU Broadcast Test System
Analog and digital TV multistandard platform with signals for antenna, satellite and cable
Satellit standards
- DVB-S, DVB-S/DSNG
- DVB-S2
- DIRECTV
DVB-S (EN 300421/EN 301210) was introduced in 1994 as a satellite transmission standard. DVB-S uses QPSK modulation. Since its introduction, DVB-S has established itself as the world's most widely used satellite transmission standard. DVB-S/DSNG also uses 8PSK and 16QAM.
DVB-S2 is an innovative and efficient channel coding method that is used in combination with high-order modulation modes. The method is very robust, offers safe reception and provides up to 30 % higher data transmission rates than DVB-S. The R&S SFU supports the broadcast service mode for non-backwards-compatible broadcast services acc. to EN302307.
DIRECTV (and DIRECTV legacy mode) is a proprietary standard with conditional access that is widely used in America and primarily in the United States. For transmission, a proprietary transport stream protocol with 130-byte packets is generated. After conversion to 188 bytes, DIRECTV transport streams can be replayed with the R&S SFU-K22 TRP player option.
