　　General

　　The TV Transmitter R&S SFQ is a complete solution for testingdigital TV links and receivers.The open-end software and modularhardware make the R&S SFQ future-proof. The standards forDVB-T, DVB-S/DVB-DSNG, turbocoding, DVB-C,J,83.-B, ATSC/8VSB andISOB-T are fully complied with. Owing to its adaptability to futuresystem changes,the R&S SFQ is a useful and rewarding investmentfor your launch onto the digital TV market.

　　Moreover,the R&S SFQ also processes analog frequency-modulatedsatellite signals in line with PAL,SECAM,NTSC standards. The soundsignals are transmitted using analog FM and digital ADR soundsubcarriers.

　　The test signals produced are of high precision and comply withthe standards,but they can also be varied and provided withpredefined errors to determine the performance of your products attheir limits. The reproducible simulation of real transmissionconditions by means of the noise generator and the fading simulatorenables the specification of modules under test.

　　Applications

　　Because of its high signal quality and versatile parametersvariations,the R&S SFQ is ideal as a source for digitalterrestrial signals(DVB-T,ATSC and ISDB-T),for testing satellite(DVB-S/-DSNG,turbocoding and FM)and digital cable links(DVB-C,J83.-B),as a standard-signal generator in development, as areference in quality monitoring,EMC labs, inspectior and testcenters and for use in production.The output frequency range allowsthe R&S SFQ to be used as a back-channel generator and coversfuture extensions of th satellite IF range.

　　Operational parameters(e.g.roll-off,puncturing rate of QAM mode)can easily be varied. For laboratory applications,valuesoutside those defined in the standard can be selected. For specialmeasurements,e..g.DVB-T,it is possible to switch offmodulation,individual carriers or groups of carriers.Sweep can beperformed over the complete RF range.

　　A shift function for frequency, level and C/N makes it possible todetermine the functional limits of the DUT,compensate for extemalmatching pads, adjust two units to give exactly the same outputsignal,etc.The advantage is that the output signal can be changedas required while the standard/nominal value continues to bedisplayed on the R&S SFQ.

　　The analog R&S SFQ sulloies frequency-modulated satellitessignals conforming to standards.Various TV standards can beselected and up to six sound subcarriers(FM and ADR)can beintegrated.In addition,external sound subcarriers can beapplied.Operational parameters are in line with standards;parameters such as amlplitude,frequency and deviation arevariable.Signals such as noise or energy dispersal can be added.Itis thus possible to test satellite links and recerivers with theaid of standard signals and to check the response to nonstandardsignals.
