  • From the broadcasting studio to the antenna, Rohde & Schwarz offers a nearly complete range of equipment and systems developed and produced by the company itself. Now one of the few remaining gaps has been closed: Rohde & Schwarz has devel-oped and launched an innovative type of headend.

    The companys initial focus for the new headends is on DVB. They revolutionize headend architecture: Instead of using numerous, separate devices, the new headends rely on extremely compact, high-performance IT hardware. All core functionality is software-implemented for high flexibility. Signal flow within the headends is fully based on the Internet protocol (IP).

    Only just on the market, the new head-ends were already prize winners: Intro-duced at IBC 2012 in Amsterdam, they won the coveted TV Technology STAR Award (page54).

  • 6R&SCMWcards simplifies the creation of wireless signaling tests2G, 3G, 4G: Developers are having to prepare an increasing number of ever more complex test cases.

    And this requires expertise in both programming and protocols. Or it did until now: The revolutionary

    R&SCMWcards user interface for the R&SCMW500 enables users to effortlessly create specification-

    compliant signaling protocol test sequences.

    Fig.1 The R&SCMW500 with the R&SCMW-CU control unit. R&SCMWcards, the revolutionary new user interface shown on the monitor, enables

    users to quickly and reliably create functional signaling sequences without programming experience.

    Customized operating concepts and programming interfacesThe R&SCMW500 wideband radio communication tester has truly earned the right to be called a multistandard test platform. Thanks to its wide range of test capabilities, the R&SCMW500 can thoroughly test user equipment for com-pliance with practically all wireless communications standards as an RF and signaling protocol tester in development or as a production tester.

    The tester comes with customized operating concepts and programming interfaces for all of these complex applications. The RF testers front panel man-machine interface (MMI), for example, has proven its value. This intuitive user inter-face gives users convenient control of measurements and

    application tests for all major wireless communications stan-dards. In R&D, the LLAPI / MLAPI programming interfaces for C++ and the TTCN-2 / TTCN-3 notation languages commonly used in conformance testing are the first choice for compli-ance testing of mobile phone protocol stacks using complex signaling sequences. However, this requires knowledge of both programming and protocols. It places an additional bur-den on developers who need to concentrate on functional tests and reproducing problems originating from real-world mobile communications networks and do not always want to deal with programming testers.

    And now they dont have to. The revolutionary new R&SCMWcards user interface, which resembles a card game, helps users set up functional signaling sequences (Fig.1).

  • Playing cards, a visual aid for setting up test procedures With the R&SCMWcards user interface, users simply drag and drop cards to create and configure wireless communi-cations cells. The cards make it very easy to represent pro-tocol procedures and to prepare and parameterize signaling sequences. A software wizard helps users arrange specifica-tion-compliant message sequences, interactively guides them through the test script and warns them of errors. There is no compilation of programming code. Once the user has finished creating the scenario, the test case can be immediately exe-cuted on the R&SCMW500.

    Clear rules and an intelligent protocol wizardLike any card game, R&SCMWcards has rules. Color-coded cards ensure that the created test sequences are always prac-tical and useful, even for highly complex protocol proce-dures. To create a specification-compliant test case, the user simply has to match the colors on the cards when setting up the sequence. This is illustrated in Fig.2. Here, the cards are placed in a correct sequence. Green is followed by green, blue by blue, etc.

    An additional aid the hopscotch wizard abstracts the dif-ferent user equipment states from the 3GPP specification into a geometric hopscotch arrangement (Fig.3). The wizard reduces the card pool, only offering the cards that put the DUT into the desired protocol state.

    Perfect overview: card types, parameterization and viewsR&SCMWcards distinguishes between different types of cards: setup, procedure, general and MMI cards. Setup cards, for instance, are used to define the environment that will be tested, e.g. network cells, SIM cards or even channel settings.

    The R&SCMWcards user interface employs an integrated approach. It combines configuration of the R&SCMW500, setup, execution and monitoring of signaling tests, and pro-tocol analysis a
