Digital TV ATSC 3.0 standard testing possible with R&S BTC unit

Digital TV receiving equipment and terrestrial tuner chipset manufacturers can test the performance of their products for compliance with the ATSC 3.0 standard using only a single unit.

Rohde & Schwarz offers an ATSC 3.0 realtime coder and a waveform testing library for its R&S BTC broadcast test center. As a reference signal generator, the R&S BTC generates the globally used TV and audio broadcasting standards, simulates transmissions and analyses the audio/video functions of DUTs in realtime.

As a realtime option, transmission parameters can be directly changed, which immediately influences signal characteristics and structure. It delivers a complete signal chain, from internal playout of an ATSC 3.0 signal via its modulation to simulating a transmission.

The R&S BTC has two RF paths and additional means of synchronisation via the STL protocol by using timestamps and a 10 MHz and 1 pps reference connection. This makes it ideal for testing equipment for compliance with the new requirements for using single frequency networks (SFN) in ATSC 3.0 networks.
