N7611B Signal Studio for Broadcast Radio

Create FM Stereo/RDS/RBDS, DAB, DAB+, T-DMB or DMB-audio test waveforms with ease

N7611B Signal Studio for broadcast radio simplifies the creation of standard-based waveforms for FM stereo/RDS/RBDS, DAB, DAB+, T-DMB and DMB-Audio component and receiver test. Easily set signal parameters and configure waveforms of up to 12 audio carriers for download and playback. Create spectrally correct FM Stereo/RDS/RDBS, DAB, DAB+, T-DMB or DMB-Audio reference signals for component test and modify physical (PHY) layer signal parameters to verify performance under various signal conditions. For receiver test, compile the RDS/RBDS/DAB/DAB+/T-DMB/DMB-Audio messages and signal information to test the data decoding function. For subjective or functional evaluation, sound-wave files, DAB/DAB+ audio files or ETI stream files can be input as payload for playback in seamless loops. Frequency error, clock error, I/Q impairments and real-time AWGN can be added to the test signal to verify receiver.
