This unit
The Rohde & Schwarz EFA93 is a TV test receiver and demodulator engineered for precise reception and analysis of analog and digital television signals across cable networks, transmitter stations, development laboratories, and quality control environments. The instrument demodulates vestigial sideband AM signals for analog TV and quadrature amplitude modulated DVB signals for digital TV, with specific design for M/N and NTSC analog standards. It measures comprehensive transmission parameters, supports terrestrial radio channel monitoring, and delivers direct transmitter quality control when deployed as a non-selective RF test demodulator.
