RWC2010B_Digital Radio Tester is
RWC2010B Digital Radio Tester supports the DAB, DAB+, DMB, DRM30, DRM+, AM, FM and RDS system. It provides very convenient working environment with full control over all system parameters. It supports various kinds of data services such as BWS, TPEG, EWS, EPG, SLS and more services will be added to adjust to changing markets. RWC2010B has ETI and MDI file player function so that specific broadcasting station’s DAB/DRM signal could be regenerated in the LAB. It also supports AM/FM radio test functions with fully editable RDS test function.
In addition, it includes an RF up-converter, which supports RF output in a range between -10dBm ~ -120dBm (CW: 0dBm ~ -110dBm) with 0.1dB step adjustable and Band LF, MF, HF, I, II, III frequency ranges, so it can directly generate broadcasting signals to DUTs so that systems can be easily aligned.
Simple testers consist of pattern player (ETI and MDI file player). Such pattern file has to be prepared in advance on external PC and then downloaded to tester. Protocol compliance tested with several combinations of configuration parameters. Every change in configuration parameters affects test pattern, so pattern file has to be regenerated on external PC and downloaded to tester again. RWC2010B is equipped with Ensemble Multiplexer. It simulates broadcast station functions. Protocol parameters can be edited using GUI program, and updated signal broadcasted immediately. RWC2010B also supports Reconfiguration, TII and announcement functions as well. Ensemble Multiplexer supports up-to 15 Services and 15 Service components for DAB/DMB and up-to 4 Streams for DRM with easy on/off. RWC2010B provides graphical ensemble information screen that can easily capture the imagination of complicate ensemble structure.
Reconfiguration, Announcement, TII
RWC2010B supports high-tech protocol tests such as Reconfiguration, Announcement and TII. Announcement is a function for a compulsory situation or automation functions. For example, if there is an emergency situation, then an announcement function is activated. This function changes the channel for every listener so that they can hear the emergency message or announcement. Alternatively, it can also be used by the user to set the channel to change to a specific program at a specific time. RWC2010B offers a screen that the user can use to change the announcement function, and it transmits announcement related FIG for DAB/DMB and SDC data for DRM for compulsive channel changing.
TII (Transmitter Identification Information) appoints an ID to every transmitter and transmits it through Null space, which is sent for every frame for various applications such as current location checking. TII can be on or off on RWC2010B. Additionally, the ID is changeable and double ID transmission is available. If two IDs are transmitted, the operation environment is also changed as if two transmitters were working at the same time.
ETI, MDI and DRM IQ File Player
The ETI file describes the characteristics of a signal suitable for transporting a full DAB Ensemble, comprising a number of sub-channels and a formatted Fast Information Channel (FIC), between the DAB Ensemble provider and the Transmission network provider. It means that if the ETI file is recoded specific broadcasting station’s T-DMB/DAB signal, it contains all information about that station’s.
The MDI file describes the characteristics of a signal suitable for transporting a full DRM Ensemble, comprising a number of streams and a formatted Service Description Channel (SDC), between the DRM Ensemble provider and the Transmission network provider. It means that if the MDI file is recoded specific broadcasting station’s DRM signal, it contains all information about that station’s. Using these files with the RWC2010B’s ETI/MDI function, that specific broadcasting station’s T-DMB/DAB signal or DRM signal could be regenerated in the LAB.
Analog AM/FM and RDS Test Solutions
RWC2010B supports analog AM/FM and RDS test functions. Most DAB/DMB/DRM DUTs support analog AM/FM features too, then it will be very useful to test not only DAB/DMB/DRM functions but also analog radio functions using one Tester. In case of FM, it supports Multi-channel FM signal generator.
Seamless Linking Test Solutions
To test Seamless Linking algorithm in the Lab, two broadcasting emulator are required. And two broadcasting emulator should be synchronized with adjustable sync delay. Using two RWC2010Bs, many combination of Seamless Linking test (DAB to DAB, DAB to DRM, DAB to FM, DRM to DRM, DRM to FM) can be performed in the Lab very easily.
Single Frequency Network (SFN) Test Solutions
To test SFN in the Lab, two broadcasting emulator are required. And two broadcasting emulator should be synchronized with adjustable sync delay. Using two RWC2010Bs, SFN test can be performed in the Lab very easily.
