General
The TV Tran***itter R&S SFQ is a complete solution for testing digital TV links and receivers.The open-end software and modular ha***are make the R&S SFQ future-proof. The standa*** for DVB-T, DVB-S/DVB-DSNG, turbocoding, DVB-C,J,83.-B, ATSC/8VSB and ISOB-T are fully complied with. Owing to its adaptability to future system changes,the R&S SFQ is a useful and rewarding investment for your launch onto the digital TV market.
Moreover,the R&S SFQ also processes analog frequency-modulated satellite signals in line with PAL,SECAM,NTSC standa***. The sound signals are tran***itted using analog FM and digital ADR sound subcarriers.
The test signals produced are of high precision and comply with the standa***,but they can also be varied and provided with predefined errors to determine the performance of your products at their limits. The reproducible simulation of real tran***ission conditi*** by means of the noise generator and the fading simulator enables the specification of modules under test.
Applicati***
Because of its high signal quality and versatile parameters variati***,the R&S SFQ is ideal as a source for digital terrestrial 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 a reference in quality monitoring,EMC labs, inspectior and test centers and for use in production.The output frequency range allows the R&S SFQ to be used as a back-channel generator and covers future extensi*** of th satellite IF range.
Operational parameters(e.g.roll-off,puncturing rate of QAM mode )can easily be varied. For laboratory applicati***,＆#118alues outside those defined in the standard can be selected. For special measurements,e..g.DVB-T,it is possible to switch off modulation,individual carriers or groups of carriers.Sweep can be performed over the complete RF range.
A shift function for frequency, level and C/N makes it possible to determine the functional limits of the DUT,compensate for extemal matching pads, adjust two units to give exactly the same output signal,etc.The advantage is that the output signal can be changed as required while the standard/nominal ＆#118alue continues to be displayed on the R&S SFQ.
The analog R&S SFQ sulloies frequency-modulated satellites signals conforming to standa***.Various TV standa*** can be selected and up to six sound subcarriers(FM and ADR)can be addition,external sound subcarriers can be applied.Operational parameters are in line with standa***; parameters such as amlplitude,frequency and deviation are gnals such as noise or energy dispersal can be is thus possible to test satellite links and recerivers with the aid of standard signals and to check the resp***e to n***tandard signals.
