          R&S launches R&S BTC, a high-end broadcast TV test system

          21ic News Rohde & Schwarz Broadcast TV Test System R&S BTC supports real-time end-to-end testing to meet all Open Systems Interconnection (OSI) requirements. The device under test (DUT) can also be integrated into a fully automated test sequence. A single device integrates many functions to meet today's and future possible transmission standards. The R&S BTC can generate and play back video and audio streams and output modulated RF signals. The R&S BTC aggregates the signal generation, the DUT embeds the video/audio analysis, and determines the picture failure point (PFP). The result is a fast, convenient, and repeatable objective image quality assessment.

          Rohde & Schwarz's new broadcast TV test system, R&S BTC, provides a complete test environment in which almost all audio, video and multimedia applications can be implemented in a single device. R&S BTC supports almost all TV and broadcast standards worldwide, and can output high quality RF signals and support various signal simulations. The R&S BTC can also analyze the real-time audio/video capabilities of the DUT. The modular design provides a high degree of scalability, allowing any customer to configure it to their requirements.

          Applications include certification and quality assurance for development, chipset and receiver manufacturers, and test facilities. Professional satellite equipment, network operators, leasing companies, regulators and manufacturers in the A&D industry will also benefit from this scalable test solution.

          The broadcast TV test system R&S BTC has two independent real-time signal paths, each with a modulation bandwidth of 160 MHz and full-scale analysis. R&S BTC supports all common digital and analog TV standards, including cable, satellite and terrestrial TV and digital/analog audio broadcasting standards, and fully supports second-generation DVB standards such as DVB-T2, DVB-C2 and DVB-S2.

          Thanks to its modular design, the R&S BTC is optimized for a wide range of tasks. It does not require expensive and time-consuming test setups, which saves on testing costs. R&S BTC's integrated automated test sequences and test suites, such as the DTG D-Book, e-book and NorDig, dramatically reduce test time for fast, reliable and repeatable testing.

          One of the main tasks in developing broadcast television equipment is to conduct anti-jamming characteristics testing. The R&S BTC covers this requirement, in addition to two independent real-time signal paths, providing up to eight arbitrary waveform generators (AWGs) for each RF path. The AWG generates complex interference waveforms that provide maximum dynamic range over the entire frequency band. In addition, realistic environmental conditions can be simulated using a variety of noise sources (wideband white Gaussian noise, pulse or phase noise), predistortion, nonlinearity, filtering, fading, and MIMO.

          Chip and tuner developers sometimes need to test with I/Q data and require highly flexible data transfer rates and data formats. The R&S BTC is equipped with a digital I/Q data interface and flexible I/Q data input/output to meet test needs.

          R&S BTC's high-resolution, 8.4-inch touchscreen display and graphical user interface for layered function blocks allow users to operate quickly and easily. The entire test setup, including signal generation, test sequence, analysis, and DUT can be graphically displayed in a GUI interface with a clear overview that even supports very complex measurement tasks. The remote control commands of the R&S BTC are compatible with the widely used R&S SFX series.

          Long lifetime and durability: based on the LED technology & the new structure, so that this lamp can reach 100,000 hours of long life in any case. Relative to the glass neon tube, its durability, because at all there is no need to consider the problem of broken glass.
