R&S UPL UPL16 音頻分析儀

Audio Analyzer R&S  UPL16 provides all the necessary audio signals and performs acoustical measurements. Digital Radiocommunication Tester R&S CMD or R&S CMU is used to establish the call. For some test cases the speech codec is also used.

Audio Analyzer R&S UPL16 has the same superior analysis concept as all members of the R&S UPL family. The instrument is able to handle both analog and digital processing. It carries out practically all types of measurement in the audio range from frequency resp***e measurements to distortion measurements, FFT analysis, etc.

All the details about test functi*** and concept of operation can be found in the data sheet of the Audio Analyzer R&S UPL. The R&S UPL16 is especially designed for acoustical tests on G*** mobiles. It is equipped with the digital audio interface (DAI) as defined in G*** phase 2 recommendation 11.10, section 36.4. Thanks to this interface the R&S UPL16 can act as a system simulator or simulate a mobile.

To drive an artificial head directly without additional amplifiers, the generator output of the R&S UPL16 is matched to the impedance of the artificial mouth by a built-in transformer on the rear panel of the R&S UPL16. G*** 11.10, section 30 defines 15 speech teleservices tests for G*** mobiles, generally referred to in this document as acoustical test cases. All these measurements are supported by the software package delivered with the instrument.
