The recording side of the RecPlay System uses the RF receiving and signal processing capabilities of the IZT R3000 Wideband Receiver Series integrated into the portable Monitoring Receiver and RF Recorder IZT R3301. Several receivers can be synchronized for antenna diversity. IZT software allows for easy storage and data/signal processing.
Recorded signals can be replayed using IZT S1000 Multi-Channel Signal Generator with system concept and hardware based on the IZT COMINT Simulator.
Operated as service or ensemble multiplexer, the system generates a DAB multiplex from all available audio signals and data services. Moreover, it enables multi-stream real-time audio encoding and handling of all standardized and proprietary DAB data applications. The IZT DAB ContentServer is based on highly available standard server hardware and on the proven software system from the renowned Fraunhofer IIS.
Benefits for Broadcasters and Network Providers
The IZT DAB ContentServer makes all options of the DAB standards family available. Different editions offer an optimal selection of features and can be extended easily to flexibly adapt to changing requirements. The compact DAB all-in-one-solution offers all necessary interfaces for smooth integration into the broadcast chain. The use of standard hardware and integrated audio coding bring the benefits of lower hardware costs, cost-efficient maintenance and a significantly lower risk of failure.
Receiver Testing with the DAB ContentServer
The Developer Edition of the IZT DAB ContentServer facilitates the development of DAB receivers. In combination with the IZT S1000 Signal Generator, a versatile laboratory setup can be achieved.
The IZT S1000 Digital multi-channel Signal Generator is the perfect source of today’s RF waveforms with increasing complexity and bandwidth.They comprise in one unit the simultaneous replaying of 31 RF signal channels and make it possible to replace extensive setups while reducing time and cost. It enables the user to consolidate multiple conventional RF generators into one compact, cost effective, flexible, and easy-to-use RF test source.
Modern radio receivers no longer gather information from a single modulated carrier, but often from multiple sources simultaneously. The multiple signals can be from more than one antenna, with independent carriers and different modulation formats. The IZT S1000 with its revolutionary architecture and IZT’s patented signal processing algorithm combines multiple technologies to match the receiver’s test requirements without a costly batch of standard RF generators.
Based on the IZT S1000 there is a model variation comprising its full functionality with extended additional memory for the most demanding application – the IZT S1010 Signal Generator.
In the IZT RecPlay recording and playback system, the IZT S1000 is used as a signal generator.
Key components of the IZT R5020 are a multichannel digitizer from IZT’s R5000 receiver series and a very high-performance, analog channelizer with overlapping bandpass filters.
IZT’s patented design outperforms conventional receivers by using a passive, low-loss channelizing filter with 12 overlapping frequency bands in front of any active electronics. Each output channel has a dedicated AD converter preceded by an electronic attenuator and subsequent low noise high linearity amplifier. Automatic gain control is performed independently for each channel. The receiver is still sensitive enough to be operated without a preamplifier.
The IZT R5020 design overcomes typical limitations of legacy receivers: Especially when large receive antenna systems are used, the input power into the receiver can be very high. In consequence, limiting the receiver bandwidth by preselection filters becomes essential. The biggest concern are second order intermodulation products which require preselection filters with less than one octave relative bandwidth.
The IZT R5509 is the ideal solution for ATC direction finding to improve situational awareness and reduce the risk of misunderstandings in radio transmissions.
The IZT R5509 DF technology avoids misreading of the aircraft’s call-sign. This improves the situational awareness of the ATC operators and increases the safety level. That in turn, allows to handle more flights per operator for costefficient control of the airspace.
The novel DF system IZT R5509 features 10 coherent receive channels and is equipped with a 9-element antenna array to realize accurate and robust direction estimation. The utilized DF antenna with 9 elements provides superior immunity to multipath propagation. An optional center antenna element may be used for even increased spatial resolution. Beyond outstanding radio frequency (RF) characteristics, the antenna is equipped with lightning protection and is verified to withstand wind speeds of 200 km/h even under icing conditions.
The available features of the IZT C3040 channel simulator were grouped into uplink, payload and downlink effects. Some features are available twice to reproduce a realistic transmission chain.
Key features:
Effects of the uplink include:
- Delay and delay change over time
- Doppler simulation
- Effects of the ionosphere
- Interference by other signals
Within the payload of the satellite the following effects are introduced:
- IMUX filtering
- Nonlinearity (AM/AM and AM/PM) caused by the amplifier
- Phase noise
- OMUX filtering
On the downlink, from the satellite to the terminal the signal then changes by:
- Effects of the ionosphere
- Large and small scale fading
- Interference by other signals
- Thermal noise
Complex operating scenarios for testing transceivers, terminals and satellites can be simulated. Effects due to modifications to the transmission method, the satellite or the terminal equipment can be simulated before implementation with the IZT satellite channel simulator.
During the lifetime of the satellites, the satellite channel simulator can be used to simulate and analyze effects and problems. IZT satellite channel simulators provide excellent signal quality and a comprehensive simulation of effects on a satellite channel.
The IZT C5040’s optimized and scalable signal processing units offer real-time simulation of influences on the signal at the satellite (non linearity, IMUX / OMUX filter, phase noise, interference, antenna gain, Doppler shift) as well as on the transmission link (interference, rain fading, scintillation, reflections, thermal noise). The state-of-the-art Graphical User Interface (GUI) allows changing all parameters of the setup easily. Remote control is possible through SCPI and SNMP.
With the IZT C5040 satellite based communication systems can be extensively simulated and tested prior to their realization. In addition, complex operational scenarios for equipment (receivers, transmitters, satellite phones) and satellite testing can be set up in a very cost-effective way. The IZT C5040 is a scalable system based on individual hardware units that can be configured from uni-directional links to bi-directional links with hundreds of terminals.
Only a single hybrid cable delivers power to the mobile sensor and transmits the data to the shelter for post-processing. This makes the installation simple, no losses in the antenna cables affect system performance and signal integrity is maintained over long distances. In the result optimum dynamic range, sensitivity and direction finding (DF) accuracy with any given antenna array are obtained.
The mobile sensor IZT R5506 contains up to six high-performance receivers up to 6 GHz. The preselector bands are matched to the frequency range of antenna elements to maximize overall system performance. One of the six channels can be factory configured with a separate local oscillator (LO) to work as an independent monitoring channel. The IZT R5506 features a high stability internal reference clock and an integrated Global Positioning System (GPS) module. All the sensor’s functions are remote controlled via the optical interface.
The sensor is provided with a DF processor as an option. Further documentation is available on request. The modular design of the IZT R5506 offers the possibility of customer-specific mechanical modifications.
The IZT R5010 uses IZT’s latest generation of tuners with sub-octave preselectors, dual conversion and a variable 1st IF for maximum robustness against false reception and high-power mixers for maximum linearity. A low-noise preamplifier can be activated for maximum sensitivity. Built-in test equipment allows for end-to-end verification and alignment of the receiver. The receiver can be operated in manual or automatic gain control mode. All internal clocks can be sychronized to an external source or the built-in GNSS receiver.
