The following theoretical performance gains are expected to be obtained in real satellite operation:.

Objectives The main objective of the DVB-S2 Satellite Experiment project is to perform an in-depth verification and optimisation by satellite of the many new features present in the DVB-S2 standard, such as high order modulations, enhanced coding and ACM, through extensive test campaigns consisting of field trials and measurements.

Features The detailed list poopback experiments has been defined to get the most consistent and valuable feedback for the verification of the new features of the DVB-S2 standard. Results are reported and published in several dissemination documents, including a feedback to the standardisation group and an article for a conference.

The RX path is returned to the same modem from the generator. More Information Accept X.

Application Test run and display of measurement results The test cases are first configured on the connected PC via the graphical user interface. On average, the E2IQ performance gap is 0.

The following theoretical performance gains are expected to be obtained in real satellite operation: The project now concentrates on the test campaigns in lab and by satellite:. Picture quality can be assessed interactively by the user or automatically by the system. Current status Phase 1 has been completed successfully, with the detailed definition of the experiments, the test-bed equipment and space and ground segments.

Many different types of measurements, including the bit error rate BERare possible. Phase 2 is dedicated to the platforms’ development, integration in labs and with the space segment in the operators? A diagram showing our hardware configuration is captured in Figure 2. Our E2IQ design comprises two main parts: This test system enables users in development or production to test and assess compliance with the various specifications, as well as the DUTs’ operability and the RF characteristics.

The experiment’s feedback should also be interesting for standardisation groups, space agencies and institutions, academics and equipment manufacturers working on the DVB-S2 subject.

Finally, the center frequency and transmit power level may be configured via the SPI bus using a modem control algorithm or by the host. The sum signal is made available to multiple instruments. Loop-back configurations allow switching to the lab environment with channel simulators. One possible error upon loading the configuration is a “conflicting instrument assignment” error, due to the PXB’s inability to configure the same signal generator on an input port and an output port.

The key topics are:.

In loopgack, new standards, or those required later, can be easily added with a software update. Taking into account outcomes from previous analysis, simulations and studies, as well as operators experience feedback and perspectives on DVB-S2, the main test areas are: The test cases have a modular structure and can be documented in easy-toreproduce, editable reports.

In phase 2, the development, procurement and integration of the test-bed platforms are mostly completed.

For signal generators that support loopback of markers, the PXB passes them through from input to output. Fraunhofer IIS Germany http: Each test campaign by satellite lasts for 3 months.

The stream adaptation block and GSE deframer blocks then remove the BB header and decapsulate back into Ethernet packets, respectively. Since existing DVB-xx loopvack are constantly being expanded and new standards added, these changes must be precisely incorporated in the design and functions of the instruments during their development and production. Phase 1 has been completed successfully, with the detailed definition of the experiments, the test-bed equipment and space and ground segments.
