Rohde & Schwarz says its EFL240 and EFL340 portable TV test receivers ?for installing and servicing receiver systems can handle cable, satellite and terrestrial television.
The new test receivers feature a variety of measurement functions for digital and analog TV standards and FM sound broadcasting. The EFL340 supports DVB-T2, the latest digital TV generation. Both instruments measure all essential test parameters and display the constellation diagram and the modulation error ratio (MER) versus frequency. In addition, the receivers can measure echoes even outside the guard interval for analyzing reception problems in multipath propagation and single-frequency networks.??
The two receivers can perform spectrum analysis in a frequency range up to 2500 MHz. The practical built-in zoom function allows service technicians to zoom in on a channel and measure it in detail while maintaining an overview of the entire TV cable spectrum.??
Video and audio content are the simplest and most direct criteria for checking reception quality. To facilitate this test, both instruments are capable of decoding MPEG-2 and displaying SD and HD programs. The EFL340 also supports MPEG-4. The common interface integrated in both receivers even makes it possible to display encrypted services. The combo mode can simultaneously displaying measurement results, spectrum and video.
