選用二手測量儀器的優(yōu)勢是：  

1、與新購儀器幾個月的供貨期相比，購買二手儀器的供貨期要短的多。在 時間就是市場的今天，優(yōu)勢無疑是最為明顯的。  

2、二手儀器的價格便宜，基本為新購儀器價格的20%～50%。在電子技術(shù)迅 速發(fā)展的今天，儀器的更新也在加快，投資越少則風(fēng)險越小。  

3、為了讓您放心地使用我們提供的二手儀器，我們銷售的二手儀器可以做到： 

      1、保修半年至一年不等。 

      2、可以根據(jù)您的要求，將儀器送至國家級計量測試單位進(jìn)行校準(zhǔn)。
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 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 in this document as acoustical test cases. All these measurements are supported by the software package delivered with the instrument.
