选用二手测量仪器的优势是：
1、与新购仪器几个月的供货期相比，购买二手仪器的供货期要短的多。在时间就是市场的今天，优势无疑是*为明显的。
2、二手仪器的价格便宜，基本为新购仪器价格的20%～50%。在电子技术迅速发展的今天，仪器的更新也在加快，投资越少则风险越小。
3、为了让您放心地使用我们提供的二手仪器，我们销售的二手仪器可以做到：
1、保修半年至一年不等。
2、可以根据您的要求，将仪器送至***计量测试单位进行校准。

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.
