R&S adding DVB-T2 standards to its T&M and transmitter systems

Rohde & Schwarz is now adding new DVB-T2 standard to its T&M and transmitter systems products.

The DVB-T2 enhances the established DVB-T standard, increases transmission capacity by more than 30 percent that improves error-protection algorithms such as low-density parity check (LDPC) codes. The error-protection algorithms ensure high reliable broadcasting coverage with DVB-T. A higher data rate per channel now allows terrestrial program transmission in HD quality. Alternatively, network operators can transmit more SD-quality programs per installed transmitter.

The R&S SFU broadcast test system features a new realtime coder option for developing and testing DVB-T2 receivers. The R&S SFU supports all code rates, bandwidths and constellations of the new standard, including the new rotated constellations Video, audio and additional data is fed to the coder as an ASI transport stream. Signals can be supplied by an external generator or the integrated transport stream generator.
