The Rohde & Schwarz UPV Audio Analyzer enables users to perform virtually all measurements that are necessary in the audio world: frequency response measurement, total harmonic distortion (THD) displays, spectral displays, analysis of digital interfaces, and much more. The generator is just as versatile. It can be used to create any conceivable signal from sinewave and noise signals up to multi-sine-wave signals. The Rohde & Schwarz UPV Audio Analyzer is an all-in-one instrument with an integrated control PC, making it easy to transport. Since the instrument comes factory-ready, it merely needs to be unpacked and switched on before being put into operation. Peripherals are therefore not required. Optional modules and software expansions that can be integrated into the instrument open up a broad scope of further applications. The UPV features an intuitive user interface (Windows XP operating system). The large screen plays a key role, not only for displaying measurement results. All settings are made in panels that contain all interrelated functions and settings. Since the operating philosophy is easy to understand and since analog and digital measurements are performed in a similar manner, users can quickly master instrument operation.
