R&S®SFL TV Test Transmitter Family
Digital signals for use in production
The high signal quality and the versatile parameter variation capabilities make the R&S SFL family ideally suited as a standard signal generator for use in production environments. The wide output frequency range allows testing beyond the limits defined by the relevant standard. The benefit of the large level range is that, on the one hand, the functional limits of LSI (large-scale integration) circuits can be quickly determined and recorded during production; on the other hand, it is easy to simulate a receive link for a TV receiver.
The operating parameters (e.g. roll-off, puncturing, QPSK mode, QAM mode, pilot level, interleaver level, etc) can easily be varied even beyond the limits defined by the relevant standard. A number of special signals or signals with predefined errors are provided in order to determine the true functional limits or to quickly detect malfunctions; it is also possible to switch off signal characteristics defined in the standard or partial signal functions (e.g. modulation, individual carriers and groups of carriers, pilot, etc).
Irrespective of the model, a sweep mode is available for the total frequency range, as well as an external I/Q input for signals with external coding.
