A signal generator used in production must have high reliability The R amp S SML meets this requirement for example through the use of a completely wear free electronic attenuator Should a fault nevertheless occur the continuous self diagnostics of the R amp S SML prevent expensive erroneous measurements Output level In production test systems the signal is taken to the DUT device under test via switches and cables thus leading to level losses These losses can be easily com pensated by the high output power of the R amp S SML Dimensions Space is often at a premium in produc tion The compact size of the R amp S SML makes it ideal for use in such environ ments Example component test To obtain reliable information on com ponent quality high level accuracy and precise reproducibility of the out put level are called for The R amp S SML fully meets these requirements owing to the level deviation of 0 5 dB at levels gt 120 dBm and high reproducibility With unrivalled short times 10 ms for frequency and level setting the R amp S SML enables fast testing and is ideal for use in production Overshoots in case of level change may damage or destroy the DUT This cannot happen with the R amp S SML since it operates without any over shoots EMS measurements Non interrupting level setting without overshoots EMS measurements call for non interrupting level setting which s

DS Coder R amp S SML B5 Signal generation and analysis with RF modulated test signal including ARI and RDS FM stereo tuner Audio Analyzer R amp S UPL Analog audio signals Audio signals are generated and measured in the Audio Analyzer R amp S UPL automatic synchronization substantially reduces the measurement time All functions of the Stereo RDS Coder R amp S SML B5 can of course be remote controlled Use of the Audio Switcher R amp S UPZ is recommended for measurements on car radios or Surround receivers with more than two audio outputs as shown in the figure on the right For more information about the Audio Switcher R amp S UPZ see data sheet PD 0758 1170 Interruption free pilot tone The R amp S SML B5 option was designed especially for use in test systems With other signal generators the stereo pilot tone is briefly interrupted if the output data has to be recalculated e g when the audio frequency changes The con nected tuner loses synchronization and has to switch to the stereo mode again with each frequency change so overall measurement time may increase dramat ically This disadvantage does not occur with the R amp S SML B5 since the audio signal is modulated onto the RF carrier independently of pilot tone generation and consequently the pilot tone is not switched off 6 Signal Generator R amp S SML Signal Generator R amp S SML Stereo RDS Coder R amp S SML
