Rohde & Schwarz BTC Tests ATSC 3.0 Device Performance

The Rohde & Schwarz BTC simulates ATSC 3.0 transmissions and analyzes the audio/video functions of devices-under-test in real-time. Equipped with a ATSC 3.0 real-time coder and waveform testing library, the BTC can thoroughly test ATSC 3.0 SFN receiver and tuner performance.

The first high-end ATSC 3.0 signal generator is the Rohde & Schwarz BTC Broadcast Test Center. The BTC includes a purely software-based real-time ATSC 3.0 coder. It also includes two RF paths which can simulate a SFN.

The two RF paths and additional means of synchronization via the STL protocol by using timestamps and a 10 MHz and 1 pps reference connection, make it ideal for testing equipment for compliance with the new requirements for using single frequency networks (SFN) in ATSC 3.0 networks.

As a real-time option, transmission parameters can be directly changed, which immediately influences signal characteristics and structure. The R&S BTC offers unique simulation functions in an all-in-one solution. It delivers a complete signal chain, from internal playout of an ATSC 3.0 signal via its modulation to simulating a transmission.

One of the main tasks when developing broadcast equipment is to test the equipment under realistic and complex transmission conditions. The R&S BTC covers this by simulating a variety of interference such as noise and fading, and wireless signals such as LTE and mobile TV.

The R&S BTC reference signal generator exhibits excellent RF performance with required parameters. Another outstanding feature is the interruption-free modulation of ATSC 3.0 signals with real audio/video/data content in real-time. It also supports internal and external sources with corresponding interfaces such as MMGen, IP (ROUTE/DASH, MMT, TS) and STL.
