Signal generators add more mobile standards

A new option for DAB and T-DMB enables Rohde and Schwarz signal generators to provide maximum test flexibility for manufacturers of mobile phones and car radios.

Using a single instrument, signals can now be generated for all conventional mobile radio standards as well as for GPS, DAB, and mobile TV via DVB-H and T-DMB standards.

Equipped with the new option, the R and S SMU200A, SMJ100A, SMATE200A and AMU200A signal generators can generate standards-compliant DAB and T-DMB signals for testing equipment such as DAB receivers in car radios, T-DMB receivers in mobile phones and components such as power amplifiers and repeaters.

Standardised ensemble transport interface (ETI) files can be used as data source, making it possible to test receivers with real audio and video sequences.

As the option runs directly on the signal generators, test settings or signals can be changed without much time or effort, also via remote control.

The signals are processed in real time, which reduces test times and increases throughput in production.

In addition, the R and S SMU200A and AMU200A signal generators offer an optional second path that makes it possible to simultaneously generate useful signals and interfering signals using a single instrument.

If the generators are equipped with a fading option, repeatable tests can be performed under real-world conditions.

Predefined fading scenarios can be quickly and conveniently set in accordance with the DAB standard, eliminating the need for complex test setups with an external fader and a PC with control software.

The R and S SMx-/AMU-K53 options for T-DMB and DAB are available now for the R and S SMU200A, SMJ100A, SMATE200A and AMU200A signal generators.

The instruments' performance is ideally supplemented by the R and S SMU/AMU-B14/-B15 fading options as well as the R and S SMU/AMU-K72 options for predefined DAB fading scenarios.
