The Rohde & Schwarz ETL TV Analyzer operates across 500 kHz to 3 GHz and functions as an integrated test platform for television and sound broadcasting signal analysis. This single instrument combines TV test receiver, spectrum analyzer, MPEG transport stream analyzer, and video/audio analysis capabilities. Field and laboratory deployments benefit from its ability to support analog standards (PAL, NTSC, SECAM), digital TV formats (DVB-T/T2, ATSC, ISDB-T, DTMB, DVB-C, J.83/A/B/C, T-DMB), and radio standards (DAB, FM).
