The Rohde and Schwarz SMCVB-K156 is the DAB/T-DMB option for the SMCV100B. This option requires the purchase of option SMCVB-K519.

The R&S SMCV100B enables you to generate signals in accordance with the Digital Audio Broadcasting (DAB)/Terrestrial Digital Multimedia Broadcasting (T-DMB) standard.

The generated signals are compliant with ETSI EN 300 401 standard. Via the user-friendly graphical interface of R&S SMCV100B, you can adjust several DAB signal parameters. You are enabled to generate a signal corresponding to one of the four standard transport modes, Transmission Mode I, II, III or IV. You can also choose to enable or disable channel coding, time interleaving, and/or pseudo noise scrambling.

The R&S SMCV100B allows you to choose between different data sources. You can either use some of the predefined data sources (two different pseudo noise sequences, fixed all “0”, fixed all “1”) or you can use your own ETI (Ensemble Transport Interface) compliant source file. To create an ETI compliant source file, you can for instance use the R&S STI Ensemble Mux DM001 or the R&S ETI Builder. However, the ETI source file must fulfill some prerequisites.

The DAB system is designed for delivery of high-quality digital audio programs and data services for mobile, portable and fixed reception from terrestrial or satellite transmitters in the Very High Frequency (VHF)/Ultra High Frequency (UHF) frequency bands as well as for distribution through cable networks.

The DAB system is designed to provide spectrum and power efficient techniques in terrestrial transmitter network planning, known as the Single Frequency Network (SFN) and the gap-filling technique. The DAB system is suitable for satellite as well as hybrid / mixed terrestrial/satellite broadcasting, using a simple, nearly omni-directional receiving antenna. The DAB system meets the required sharing criteria with other radio communication services.
