R&S®SFE100 Test Transmitter

The powerful broadcast signal generator for production test systems

Applications

Test systems in consumer electronics and automobile production

The R&S®SFE100 is an ideal choice for such applications, combining a baseband signal source, a modulator and a power amplifier in a single unit. This significantly reduces test system complexity. The advantages are obvious: Systems using the R&S®SFE100 are more cost-effective; smaller in size, more reliable and easier to service than conventional solutions. Plus, they require fewer replacement units than similar competitive solutions. And last but not least: They considerably cut down on energy consumption.

To comply with the wide range of transmission standards, producers of consumer electronics - such as set-top boxes and TV sets - , require a variety of test signals at different frequencies and with different contents. The signals are delivered by signal generators, which are usually accommodated in a separate room. A coupling network combines the signals and distributes them to the individual test stations in the factory via cable, partly over considerable distances. A baseband signal is generated for each channel, modulated onto the appropriate RF and amplified as required for distribution. In conventional systems, this process requires three different instruments – a baseband generator, a modulator and a power amplifier.
