Integration of spectrummeasurementsin TV and soundbroadcasting signalanalysisAt a transmitter, at a cable headend and in the field, a spectrumanalyzer is always necessary because it is a universalT&M instrument which can be used to check a series ofinfluences and conditions that could adversely affect signaltransmission. The R&S®ETL eliminates the need for a separatespectrum analyzer and test receiver. The R&S®ETL includesa complete spectrum analyzer that can be operateddirectly from the TV Analyzer/Receiver mode or all or justfor certain measurements. Efficient integration of a spectrumand TV analyzer in a single instrument saves time.There is no need to connect and disconnect between twoT&M instruments. Automatic measurements can be madeand documentation is easier.Full-featured spectrum analyzerThe R&S®ETL can operate as a full-featured spectrum analyzer.Up to four markers, including noise, phase noise anddelta markers, are available in this operating mode. Variousresolution and display bandwidths, as well as detectors,can be flexibly set. In addition to the normal spectrum display,other measurements that are of great interest to networkproviders are offered.Adjacent channel power (ACP) measurement.Transducer editor.Harmonics measurement.Complementary cumulative distribution function (CCDF) measurement.32
Measurement of transmission channel power,adjacent channel power and harmonicsIt is of fundamental importance that TV signals be broadcastat a defined power, while affecting adjacent channelsas little as possible. The R&S®ETL provides measurementsfor determining the channel power, the power in adjacentchannels, and harmonics. The settings can be predefinedby the user and saved for repetitive use.Crest factorFor digital transmission standards, the output power is deliberatelylimited in order to operate transmitters and modulatorsin an energy-efficient manner. The crest factor is ameasure of how the output power is limited. The crest factorcan be measured and displayed in both the spectrum andTV analyzer modes. An advantage of the TV analyzer modeis that all the needed settings are predefined according toa specific standard.Built-in tracking generator for measuring filters andamplifiersThe R&S®ETL comes with a tracking generator as standard.The output power of the tracking generator can be setbetween –20 dBm and 0 dBm in 1 dB steps. The trackinggenerator can be used to quickly check filters and amplifiersand determine their transfer function, without the need for aseparate signal source.Transducer tables and antenna factors taken intoaccountTransducer tables can be used to correct measured values.For example, frequency-dependent attenuation andamplifier characteristics are taken into account duringmeasurements. This function is very useful for coveragemeasurements in the field. Frequency-dependent antennafactors for test antennas can be conveniently entered andconverted to field strength values using the measured inputlevels.The output spectrum of a terrestrial transmitter usually hasdefined limits. Adherence to these limits can normally onlybe tested with a high-end spectrum analyzer that has asufficiently high dynamic range. As a rule, such spectrumanalyzers are too large, too heavy and do not have the TVspecificfunctions required for field use. The R&S®ETL isthe ideal compromise.Using the convenient copy function, a channel filter's passbandcharacteristic, which was recorded by the R&S®ETLand its integrated tracking generator, can be easily andreliably transferred to a transducer function which is takeninto account in the transmitter's measured output spectrum.Values that would be outside the dynamic range of theR&S®ETL can be checked in this way.Frequency spectrum without transducer function.Frequency spectrum with transducer function.Rohde & Schwarz R&S®ETL TV Analyzer 33
