The Rohde & Schwarz EFA89 is a test receiver engineered for RF component and system characterization across laboratory and field environments. It delivers precise S-parameter, impedance, and network parameter measurements alongside real-time signal analysis capabilities. The instrument supports demodulation of both digital broadcast standards (DVB-C, DVB-T, ATSC) and analog TV signals (VSB AM), making it suitable for development, production, and field testing workflows.
