For the true qualification of QAM modulators or head-ends, choose the R&S EFA73 and use its power for MER results of up to 47dB. This unit can be fitted for the ITU-T J.83 Annex B standard (US Cable QAM), as well as for DVB-C (ITU-T J.83 Annexes A and C), and can be extended for analog NTSC/BTSC and ATSC 8VSB operation.

The new portable R&S® FSH3-TV combines the functions and features of a complete RF spectrum analyzer up to 3 GHz, with those of a TV test receiver in a single measurement instrument, and is ideal for installation, maintenance or repair work, on TV cable networks or transmitters. It comes equipped with a TV demodulator, a preamplifier and a tracking generator, and permits measurements of analog and digital TV signals, including NTSC, 8VSB and US-Cable QAM (J.83/B). A demodulated CCVS (analog TV) or as a TS-ASI (digital TV) output is provided. For use in cable networks or as a TV test receiver, a Preselector with a 75 Ohm input is available, which improves the usable dynamic range.
