R&S®EFA50/53 Test Receiver (ATSC)
All measurement functions for ATSC digital TV standard
R&S EFA-ATSC/8VSB for production of modulators and transmitters
The R&S EFA's analysis capabilities permit indepth testing of the transmitter's performance thanks to the outstanding MER/EVM dynamic range, amplitude distribution measurement and spectrum analysis - integrating the automatic shoulder attenuation measurement according to FCC recommendations.
Monitoring of ATSC/8VSB transmitters and transposers
The R&S EFA is the perfect solution for monitoring ATSC/8VSB signals. An alarm is triggered if one of the selected parameters exceeds the set threshold (all thresholds can be individually configured): incident level, ATSC/8VSB synchronization, MER (modulation error ratio), EVM (error vector magnitude), BER before Reed-Solomon decoder and MPEG2 TS data error can be checked in realtime independently of other measurements and decoding. If an error occurs, a 1000-line register is available for recording the date, time and description of the event.
R&S EFA ATSC/8VSB as relay receiver
For this special application, the R&S EFA is simply optimized for reception at a keystroke - adding a special filter in order to remove any analog M/N co-channel interferers. This allows reception even under adverse operating conditions. The user is also able to configure the bandwidths of the main amplitude- and phasecontrolled loops.
R&S EFA as a multistandard digital and analog platform
Since the analog terrestrial standard M/N is still in use, and broadcasters need a future-proof solution for their short- and long-term investment based on an R&S EFA ATSC/8VSB receiver, an analog M/N NT-SC/BTSC demodulator can optionally be implemented. It covers all application areas from R&D to field measurements. Furthermore, to protect your investment, the unit can be updated by means of options to demodulate and analyze the ITU-T J.83/B and DVB-C digital cable standards. These unique features make the new EFA family members THE measurement devices for the present and the future.
