Rohde & Schwarz's new family of signal generators—including the R&S SFE100, R&S SFE, and R&S SFU—is all an engineering team needs for development, service, quality assurance, and production of broadcast receiver instruments.
To achieve maximum versatility, the instruments are cross-compatible and complementary. All conventional broadcasting standards are supported: analog or digital, terrestrial, satellite, cable, mobile TV, and digital sound broadcasting.
The R&S SFE100 test transmitter is a single-standard instrument specifically for production applications. The compact R&S SFE broadcast tester is a versatile and cost-efficient multi-standard generator for a wide variety of applications in the lab, in service, and in the factory.
The multi-standard R&S SFU broadcast test system offers comprehensive simulation and analysis functions is a high-end instrument for complex applications in development.
The R&S SFE100 is a test transmitter used during the production of broadcasting terminal equipment. It delivers an attractive price/performance ratio and combines an RF signal generator, power amplifier, and baseband generator in a single instrument.
As a single-standard test transmitter, the R&S SFE100 is available in several models for all common TV standards and many sound broadcasting standards. It uses real-time coding or operates as an arbitrary waveform generator.
Its integrated power amplifier makes the instrument especially suitable for use in production test systems. The R&S SFE100 is an easy to use, cost-efficient broadcast signal source but it can also be used for special applications as a second RF channel for the R&S SFU.
Up to three standards can be installed simultaneously in the R&S SFE broadcast tester. The generator combines an RF modulator, a universal real-time coder, and baseband signal sources in one instrument. In this configuration, it can generate broadcast signals in the frequency range of 100 kHz to 2.5 GHz in real-time.
Its modular design makes it ideal for a wide variety of lab applications as well as for service and quality assurance. Because it includes a noise generator and BER tester, the R&S SFE also handles more complex measurement tasks.
The R&S SFU broadcast test system is the high-end instrument of the family and can be used to develop and extensively test new digital broadcasting transmission methods. It provides high-precision standard signals, permits signal modifications up to the system limit, and can insert defined errors.
The R&S SFU can easily be upgraded to accommodate changes in broadcast standards. It combines a test transmitter, a signal generator/recorder for MPEG-2 transport streams, a fading simulator with up to 40 paths, a broadband digital AWGN noise source, and an ARB generator in a single platform.
The R&S SFU is suitable for research and development as well as for quality assurance and EMC measurements. The compatibility of the commands between instruments allows test scenarios and remote-control programs created using the R&S SFU to be immediately transferred to the R&S SFE100, which saves time and minimizes errors.
