Characteristics

The R&S SFE100 is a single-standard test transmitter with realtime coding for broadcast signals. R&S SFE100 models are available for all common TV standards and a number of sound broadcasting standards.

The R&S SFE100 is a compact and reliable instrument that can be equipped with a power amplifier unique in this class, making it particularly valuable in production test systems. Plus, it can be used as a simple and economical signal generator as well as for special applications as a second RF channel for the R&S SFU.

Every R&S SFE100 model can be equipped with the appropriate digital or analog baseband signal source with which test signals from Rohde & Schwarz libraries or customer-specific test signals can be replayed. The R&S SFE100 thus combines two functions in one box, thereby significantly simplifying complex production test systems.

The R&S SFE100 model with an arbitrary waveform generator enables you to generate modulation signals of any type and to replay customer-specific waveform files, irrespective of the available realtime coder models.

Occupying only one height unit, the R&S SFE100 is extremely compact. Nevertheless, all functions can be selected locally on the instrument. Alternatively, the R&S SFE100 can be remote-operated from a PC. In this case, operation is performed using the same convenient graphical user interface as for the R&S SFE and R&S SFU.

Applications

In the production of broadcast consumer electronic equipment such as set-top boxes and televisions, a number of test signals for various transmission standards are required at various frequencies and with different contents. The required signal generators are usually kept in a central transmitter room. The signals are combined in a coupling network and distributed to the individual test stations in the factory via cable, partly over considerable distances. For each channel, a baseband signal is generated, modulated to the corresponding RF, and then amplified to a sufficient level before being fed to the distribution network. This task normally requires three different instruments – baseband generator, modulator, and power amplifier.

The R&S SFE100 is optimally designed for this application: It combines the baseband signal source, modulator, and power amplifier in only one instrument. This makes such a system far less complex. The advantages are readily apparent: A system with the is not only more economical; it also requires less space, is more reliable, easier to maintain, and involves less spare equipment.
