RedwoodComm

2 RWC2010B DAB, DAB+, DMB, DRM30, DRM+, FM, AM, RDS in one box

3 Key Feature (1/3) Function Description DAB/DAB+/DMB Ensemble MUX
Support Band II/Band III/ Built-in Ensemble Multiplexer Easy and Flexible Ensemble Editing Up to 15 service components Various functional Test: Reconfiguration, Announcement, TII, etc.. DRM30/DRM+ Ensemble MUX Support LF/MF/HF for DRM30 and Band I/II/III for DRM+ Up to 4 Streams Various functional Test: Reconfiguration, TIME, etc.. Analog AM/FM RDS FM(Mono/Stereo/Wave), AM(Mono/Wave) Test function Support RDS test, most protocol parameters are editable in GUI ETI/MDI player Downloaded ETI(DAB/DAB+/T-DMB), MDI(DRM30/DRM+) file play function Seamless Linking Test Two RWC2010B testers are connected by data cable and synchronized automatically Powerful Linking Test functions DAB-DAB, DAB-DRM, DAB-FM, DRM-FM, DRM-DRM, FM-FM SFN Test Two RWC2010B testers could transmit synchronized signal The delay adjustable with 0.1us resolution

4 Key Feature (2/3) DAB/DMB DRM Support all TX Mode: I, II, III, IV
Configurable Ensemble Max 15 services, 15 service components Easy Configurable Components DAB, DMB, DAB+, BWS, TPEG, EWS, etc… Functional Tests Reconfiguration, Announcement, TII, Time, etc… DRM Robustness Mode: A, B, C, D, E Bandwidth option (kHz): 4.5, 5, 9, 10, 18, 20, 100 Modulation parameters: 64QAM, 16QAM, 4QAM Protection Type: UEP & EEP Easy Configurable Service structure Max 4 services, 4 streams Reconfiguration, Announcement, Time, etc…

5 Key Feature (3/3) Analog FM/AM RDS/FM/AM Mono FM Radio Test function
Stereo FM Radio Test function Independent Left/Right audio tone frequency AM Radio Test function Wave music file Player function This function is very important for Seamless Linking Test RDS/FM/AM Configurable RDS protocol Parameters Support many functional test Traffic program, Traffic announcement, EON FM to FM Linking Test with two RWC2010B

6 RF Specification Frequency Level VSWR LF/MF/HF Bands: 150kHz

65MHz BAND II: 87MHz

108MHz BAND III: 174MHz

230MHz Resolution: 1kHz Stability: 1ppm Level Range: -10dBm

-120dBm for BAND I/II/III Range: -20dBm

-120dBm for LF/MF/HF BAND Resolution: 0.1dB Accuracy: +/- 1dB VSWR 1:1.5 or better

7 Built-in Ensemble Multiplexer
Add Services in Ensemble Move the cursor on the service and set as ‘ON’ Add New Service It is very simple ! But powerful !

8 Built-in Ensemble Multiplexer
Add Secondary Component Move the cursor on the service and select ‘EDIT’

9 Built-in Ensemble Multiplexer
Change Component Move the cursor on the Component and select ‘EDIT’

10 Built-in Ensemble Multiplexer
Modify other protocol parameters as you want

11 Still receiving from DAB Without audio discontinuity
Seamless Linking Test Service Linking: Just switching channel  make audio discontinuity Seamless Linking: Switching channel without audio discontinuity Easy Seamless Linking Test using two RWC2010B One Tester works as a Master and the other works as a Slave Provide Audio Time Delay adjust parameter between two units MASTER Still receiving from DAB Receiving from DAB Receiving from FM Without audio discontinuity DAB Sync Cable SLAVE FM with RDS Master & Slave are broadcasting synchronized the same audio

12 Single Frequency Network (SFN)
Easy emulate SFN environment using two RWC2010B One Tester works as a Master and the other works as a Slave Two RWC2010B transmit exactly synchronized signal Signal delay adjustable with 0.1us resolution MASTER DAB Sync Cable SLAVE Receiving signal from two RWC2010B DAB Master & Slave are broadcasting synchronized signal

13 Before Reconfiguration After Reconfiguration
Reconfiguration Test Provides the required mechanisms for changing the multiplex configuration whilst maintaining continuity of services Before Reconfiguration After Reconfiguration

14 Announcement Test Configurable Announcement support parameters
ASU_FLAG: Announcement Support Flag ASU_CLUST: Announcement Support Clusters (up to 5) Easy to Switching Just Set the ‘SWITCHING’ parameter as ON Radio A Radio B BWS Listening different services Warning Radio Listening the same radio

15 DAB TII Configuration Easy Turn On/Off TII signal
Configurable TII Parameters TII_PATTERN (MAIN_ID) TII_COMB (SUB_ID) frame frame frame NULL REF FIC MCS TII REF FIC MCS NULL REF FIC

16 ETI/MDI File Player RWC2010B combines ETI/MDI file player and COFDM Modulator functions in one box. ETI File describes full DAB ensemble, comprising a number of sub-channels and a formatted FIC Regenerate the specific broadcasting station’s signal in the LAB MDI File describes full DRM ensemble, comprising a number of streams and a formatted FAC/SDC Support two ETI file format ETI(NI, G.703) / ETI(NI, V11) ETI/MDI File information Screen

17 PC Program (Streaming)
Real time file transfer function from PC to RWC2010B Very easy to test many contents files with out downloading Send contents file in real time Generate Ensemble in real time Ethernet cable

18 PC Program (Remote Control)
All functions of RWC2010B can be controlled by remote PC through LAN Using this function, RWC2010B can be placed very far from your desk Ethernet cable

19 Competitor (DRM) Fraunhofer (German) Advantage of RWC2010B
DT230 Only for DRM30 (100KHz

27.4MHz) Just MDI File Player DT4030 Only for DRM+ (5MHz

170MHz) Advantage of RWC2010B Support DAB, DAB+, DRM30, DRM+, RDS, AM, FM in one box Self Ensemble Multiplexer function Easy and powerful Protocol Test ETI/MDI File Player function Support Reconfiguration, Announcement, Seamless Linking test One Box Solution!
