The Rohde & Schwarz UPV is a high-precision audio analyzer integrating signal generation and measurement within a single instrument. Built around an embedded Windows PC, it operates standalone without external peripherals, delivering comprehensive testing across analog and digital audio interfaces. The UPV measures frequency response, total harmonic distortion (THD), spectral content, and digital signal characteristics essential for audio equipment development and quality control. Its intuitive graphical interface supports simultaneous multi-function measurements, real-time data display across up to 16 channels, and user-programmable measurement sequences for automated testing workflows.
