EFA – the test reference for terrestrial digital TV
In order to broadcast TV programs with optimum quality and in compliance with DVB-T standards, all components of the transmission chain must be of high-grade design. But not only does the quality of the components play a major role. It must also be ensured that all components operate in the specified ranges and that possible problems are detected early on. In this context, the DVB-T models of the EFA family of test receivers meet the demand for highprecision reception measurements. Compact in design and featuring comprehensive automatic test functionality, the instrument is ideal for R&D, modulator production testing, and in-service monitoring of TV signals.
