The Best Rohde & Schwarz UPL16
Rohde & Schwarz UPL16
GSM Audio Analyzer
Audio Analyzer Rohde & Schwarz UPL16 provides all the necessary audio signals and performs acoustical measurements. Digital Radiocommunication Tester Rohde & Schwarz CMD or R&S CMU is used to establish the call. For some test cases the speech codec is also used.
Audio Analyzer Rohde & Schwarz 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 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 Rohde & Schwarz 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 Rohde & Schwarz 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 in this document as acoustical test cases. All these measurements are supported by the software package delivered with the instrument.

Description
Rohde & Schwarz UPL16
Audio signal processing without digital technology is no longer conceivable. Yet, analog technology is still present and constantly being improved. State-of-theart measuring instruments must therefore be able to handle both analog and digital signal processing.
The Audio Analyzer Rohde & Schwarz UPL performs virtually every type of analog measurement:
frequency response measurements; externally controlled sweeps with reference traces; determination of 3rd order difference frequency distortion; or spectral display of demodulated wow and flutter signals.
In contrast to many other audio analyzers, the Rohde & Schwarz UPL can perform real dual-channel measurements in the audiofrequency range, i.e. there is no need for switchover between two inputs and this type of measurement is not limited to a few special cases.
The generator is equally versatile: it supplies any conceivable signal whether sinewave, noise signals, or multi-sinewave signals comprising up to 7400 frequencies.
In addition, the R&S UPL features excellent technical data: analog sinewave generation with harmonics of typ. −120 dB;
spectrum displays with a noise floor
below −140 dB for analog and −160 dB
for digital interfaces; and FFT with a maximum frequency resolution of 0.05 Hz.
