2 R&S®SFE Broadcast Tester Version 02.01, August 2008
Introduction
The R&S®SFE is a multistandard-compatible broadcast signal generator that supports all common TV standards and a number of audio
broadcasting standards. Whether analog or digital terrestrial TV, cable, satellite or mobile TV, digital and analog audio broadcasting – all
these signals can be generated in realtime. For this purpose, the R&S
realtime coder, and a baseband signal source in a single instrument.
Owing to its modular concept, the R&S
®
SFE can be optimally adapted to the specific conditions – e.g. with an integrated noise
generator or a BER tester. By installing software options, the R&S
new modulation modes. This can be done on-site and without having to open the instrument.
The versatile baseband signal source for digital TV standards allows the generation of test signals from Rohde & Schwarz libraries and
the replay of customer-specific transport streams. For analog TV, the R&S
Alternatively, both transport streams and analog A/V signals can be fed in by external baseband generators. Irrespective of the realtime
coders used, an ARB waveform generator can be used to generate any modulation signal needed and to replay waveform files of the
customer.
The R&S
®
SFE is compact and space-saving in design. It offers the same convenient graphical user interface as the high-end R&S®SFU
as well as comprehensive remote-control options.

Specifications
Specifications apply under the following conditions: 60 minutes warm-up time at ambient temperature, specified environmental
conditions met, calibration cycle adhered to, and all internal automatic adjustments performed. "Typical values" are designated with the
abbreviation "typ." These values are verified during the final test but are not assured by Rohde & Schwarz. "Nominal values" are design
parameters that are not assured by Rohde & Schwarz. These values are verified during product development but are not specifically
tested during production.
Rohde & Schwarz equipment is designed for reliable operation up to an altitude of 2000 m above sea level, and for transport up to an
altitude of 4500 m above sea level.
