Rohde & Schwarz announces R&S ETL TV analysers

Rohde & Schwarz will present a new universal multistandard platform for analysing TV signals.

Rohde & Schwarz will present a new universal multistandard platform for analysing TV signals. The R&S ETL combines the functionality of a TV test receiver and spectrum analyser in a single instrument while maintaining high measurement accuracy. This innovative instrument concept allows new TV standards to be implemented on a software and hardware basis. Thus, digital TV standards such as DVB-T/H as well as analogue TV standards can be integrated in only one instrument. Rohde & Schwarz will continue using realtime demodulation with the R&S ETL. The TV analyser platform is especially suitable for commissioning, installing, and servicing TV transmitters as well as coverage measurements for terrestrial TV and measurements on CATV head stations. With only a single unit, broadcast transmitters or CATV systems can be easily and accurately installed and cost-effectively maintained. The platform's compact and robust design makes it ideal for mobile applications, greatly simplifying the measurement of network coverage.

Both the software- and hardware-based demodulators generally work in realtime. Thus, the R&S ETL is currently the only TV analyser in its class that consistently performs BER measurements in realtime and makes complete analyses.

Using realtime demodulators has the advantage that demodulated analogue video and audio signals as well as digital MPEG transport streams are available for further processing.

The frequency range of the analyser is from 500 kHz to 3 GHz.
