Rohde & Schwarz UPL16 Audio Analyzer, DC to 110 kHz
The R&S UPL16 Audio Analyzer provides all the necessary audio signals and performs acoustical measurements GSM Mobile phone audio testing. The CMD80 or CMU200 Digital radio Communication Tester is used to establish the call. For some test cases the speech codec is also used.
The R&S UPL16 Audio Analyzer 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 response measurements to distortion measurements, FFT analysis, etc.
All the details about test functions 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 GSM mobiles. It is equipped with the digital audio interface (DAI) as defined in GSM 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. GSM 11.10, section 30 defines 15 speech teleservices tests for GSM mobiles, generally referred to as acoustical test cases.
