Rohde & Schwarz adds mobile standards to test equipment
The R&S SFU TV test platform from Rohde & Schwarz now generates test signals for all mobile digital TV standards — including DVB-H, T-DMB, ISDB-T, DMB-TH and MediaFLO — on a single platform.
Equipped with the new optional ISDB-T coder, the R&S SFU allows testing of digital short-wave transmission or DRM (Digital Radio Mondiale). It enables realistic simulation of mobile propagation and adjacent channel occupation.
By integrating the ISDB-T standard into the R&S SFU, which includes a real-time encoder, the user can generate T-DMB/DAB, ISDB-T or MediaFLO signals. In addition, the instrument provides a T-DMB/DAB library containing a wide variety of ETI streams. One of the new options is the R&S SFU-K353, which incorporates a comprehensive test signal library using waveforms for DRM.
For real-world propagation tests, special functions such as noise superposition or fading simulation make it possible to generate complex test signals in real time. Mobile TV scenarios with adjacent channel occupation are described in the IEC62002 standard — also called MBRAI standard — as well as in D-Book, NORDIG and A.74. Using the enhanced R&S SFU-K199 analog TV option and the R&S SFU-K354 digital interferer option, users can simulate these scenarios.
The R&S SFU system platform is suitable for a wide range of applications from research and development, production, quality assurance and service to EMC measurements and propagation and reception tests by network operators.
