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

Acceptance testing,maintenanceand servicing of TV,mobile TV, DAB andFM transmittersThe quality of transmitter networks depends on the optimaland error-free operation of each individual transmitter. TheR&S®ETL TV analyzer offers a range of functions to maintainthe high quality of the network during acceptance testing,maintenance and servicing of transmitters. The same holdstrue for cable TV networks and their modulators used incable headends.Precise analysis of the signal quality at thetransmitter outputThe R&S®ETL's high-quality RF frontend and subsequentdigital signal processing help ensure accurate, closetolerancemeasurement results. A contributing factor isthe R&S®ETL system performance, with a video signal-tonoiseratio of > 60 dB (analog TV) and an intrinsic MER of> 40 dB (digital TV), providing enough margin for measurementswith relatively low inherent error. The precision of theR&S®ETL can be increased by using an internal temperaturecompensatedoscillator or external power sensors supportedby the R&S®ETL.Measurements to optimize transmitter operatingparametersThe R&S®ETL measurement functions are not limited to afew key parameters. The TV analyzer also provides othermeasurements that help the user optimally set up theoperating parameters, such as frequency spectrum, modulationparameters and output power.Measurement of spurious emissionsSpurious emissions at the transmitter or cable headendmust be measured to make sure adjacent channels arenot adversely affected. One of the main advantages of theR&S®ETL is the built-in spectrum analyzer functionalitythat makes it possible to measure shoulder attenuation,adjacent channel power and harmonics without additionalmeasurement equipment.Detection of faultsThe very difficult task of finding sporadic faults is easy withthe R&S®ETL. Fast realtime signal processing captures evensporadic interference. The measurement log option is especiallyuseful. Important parameters are logged even overlonger time periods. Deviations from nominal values areclearly shown.Documentation of signal parametersThe R&S®ETL offers various options for documenting signalparameters. It only takes seconds to create and savescreenshots, either internally or to an external storagemedium. These tasks can be conveniently accomplishedwith the R&S®TxCheck measurement software. Thesoftware automatically measures DVB-T, DVB-T2, DVB-H,ATSC/8VSB, ISDB-T (B), DVB-C, J.83/B/C and FM (radio)signals, evaluates the results and documents them in areport.Remote maintenance via IP networks with theRemote Desktop functionA service technician is not always available at the transmittersite to quickly analyze the cause of faults. In this case,the R&S®ETL can be controlled remotely via a LAN interface.The Remote Desktop function allows specialists to carryout all measurements from a remote location, such as acentral service center, as if they were on site.6
