R&S®ETL TV Analyzer - Product Brochure - Rohde & Schwarz

Comprehensive analysisof digital TV andmobile TV signalsThe most important parameters at a glance (DVB-T, DVB-H).Digitization has made the production of multimedia contentmuch easier – from recording to postprocessing andarchiving. Highly efficient digital transmission methods areused to bring such produced content to the receiver, ideallywith no loss in quality. A range of parameters needs to betaken into account.Overview of the most important parametersThe R&S®ETL TV analyzer provides users with a compactlist that gives a quick overview of the key parameters.Only the parameters relevant to the selected standard aredisplayed. Predefined limits for almost every parameteralso help personnel with little training evaluate the signalquality.Essential parameters are permanently displayed in a footer,even after changing to another measurement. Theseparameters include the level, MER, bit error rate and thestatus fields for synchronizing to the carrier signal or thedigital transport stream. As a result, users do not haveto continually switch between the various measurementscreens, and alignment is easier.Spurious emissions quickly detected with integratedspectrum analyzerFor digitally modulated transmissions, it is vital to ensure thatadjacent channels are not adversely affected by spuriousemissions. A transmitter operator must always observe certainstandard-specific criteria. Typical criteria are, for example,defined shoulder attenuation within specified frequencyranges, output-power-dependent spectrum masks and leveldifferences defined for specific frequencies.Constellation point with color display of frequencydistribution of individual symbols.The R&S®ETL provides a choice between standard-compliantpredefined measurements and the flexible use of theintegrated spectrum analyzer.Constellation diagram of a DVB-T, DVB-H signal.Constellation diagram of an ISDB-T signal.16
