Test and measurement for broadcasting

Rohde & Schwarz T&M solutions ensure reliable installation and maintenance of infrastructures for terrestrial and wired distribution of broadcast content and internet data.

Supplying as many subscribers as possible with TV, radio and internet data over a large coverage area requires a suitable infrastructure that meets reliability, efficiency and quality requirements. It is usually necessary to comply with regulatory requirements during operation to avoid unwanted interactions with other services.

Broadcast receivers from Rohde & Schwarz help users implement and comply with requirements and regulations when installing, maintaining and operating such infrastructures.

Terrestrial networks and transmitters | Rohde & Schwarz

Terrestrial networks and transmitters

Depending on the topography of the coverage area, terrestrial broadcasting of signals can be a challenge. Effects such as shading and multipath reception caused by elevated terrain and buildings can adversely affect the reception of broadcast signals. To counteract this, today transmitter networks are often designed as single-frequency networks. The operation of a single-frequency network places stringent demands on complying with the specified transmit power, transmit frequency, signal feeding and signal propagation times. It is also necessary to ensure that each transmitter transmits only within its assigned frequency spectrum.

The R&S®ETL and R&S®ETC TV analyzers both offer all the measurements required when installing and maintaining broadcast transmitters.

Used together with the TV analyzers, the R&S®BCDRIVE drive test software helps users detect coverage gaps in the transmission area, providing the basis for optimization.

CATV networks and headends | Rohde & Schwarz

CATV networks and headends

Notwithstanding the trend to increasingly consume radio and TV programs over the internet (mobile communications, DSL), numerous hybrid fiber coax (HFC) cable TV networks continue to be operated, upgraded and expanded worldwide. Since the 1990s, cable TV networks have also been transmitting internet data (in line with the DOCSIS standard) between the cable headends and the end users' cable modems in parallel with the "classic" TV signals.

The DOCSIS 3.1 standard currently represents the highpoint of technological development for transmitting internet data in HFC cable networks. Today headends feed cable networks almost exclusively with digital TV signals, which are likely to be replaced by DOCSIS 3.1 IPTV signals in the medium to long term. To analyze DOCSIS 3.1 signals at the headend or in the cable TV network, users can choose between the R&S®FSW high-end spectrum analyzer with its DOCSIS 3.1 options and the R&S®DSA real-time DOCSIS signal analyzer.

The R&S®ETL is ideal for analyzing classic broadcast signals and offers analysis functions for digital TV, analog TV and FM radio signals.
