R&S®UPV

Audio Analyzer

Compact instrument for all audio measurements

The R&S®UPV 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-sinewave signals.

The instrument features scalable graphical windows that can be moved around on the screen as needed, providing all measurement results at a glance. Results can be displayed in realtime for one or both channels and can optionally be expanded to a maximum of 16 channels. Multiple measurement functions/graphics are available simultaneously. For example, analyses in the frequency and time domains can be displayed at the same time. With graphics, results can be read off using vertical and horizontal cursors, and limit lines or stored measurement results can be superimposed on them or compared with them.
