简介
尽管音频信号目前主要是通过数字方式处理的，但模拟技术不断增强，仍然不失为行之有效的替代方案。 如此一来，模拟和数字测量缺一不可。 R&S®UPV 音频分析仪是专门为此设计的。
主要特点
特性
The Rohde & Schwarz UPV Audio Analyzer features the ability to measure analog interfaces. Although audio signals are mainly processed digitally today, analog technology remains a viable alternative that is continues to be enhanced.
The R&S UPV performs nearly all measurements that occur in the audio world, ranging from frequency response measurements through distortion and spectral display to the analysis of digital interfaces. Several measurement functions can be performed and displayed simultaneously; in contrast to numerous other audio analyzers, all measurements in the audio frequency range are performed as true dual-channel measurements, cutting the measurement time for stereo applications by half.
The UPV generator is just as versatile, creating any conceivable signal from sinewave to noise; these signals can also be output with a user-selectable nominal frequency response.
The generators of the R&S UPV create a wide variety of analog and digital test signals (digital requires option B2):
The Rohde & Schwarz UPV Audio Analyzer provides extensive measurement functions on analog and digital (option B2) interfaces:
