Signal generator handles DVB-T/H and HD-radio

Full suite of channel impairments is built-in

IZT is a spin-off of the Fraunhofer Gesellschaft, the German institution for applied research, making radio monitoring, test and measurement and broadcast products. Its IZT S2000 signal generator is now able to simulate digital broadcast, DVB-T, DVB-H and HD Radio signals. For DVB-T/H the IZT S2000 offers the complete signal processing chain in real-time: from DVB-H compliant coding over transport stream multiplex, channel coding and modulation to real-time simulation of the signal impairments and propagation effects between transmitter and receiver. The user can carry out tests using a graphical user interface, a remote interface or built-in programmable test scenarios. When equipped with the new 'HD Radio waveform' option, the IZT S2000 generates test signals for HD Radio broadcasting both for AM and FM bands. The test vectors are streamed directly from hard drive.
The signal generator is able to simultaneously generate two different standards. Signals for other standards can be produced using the built-in 4 Gbyte-deep arbitrary waveform generator; if produces signals in real-time. To create impairments the IZT S2000 has features such as AWGN, profile, non-linearity, output filter simulation and a fading channel simulator to emulate small scale fading and multipath propagation.
