The Rohde & Schwarz UPV66 is a high-performance audio analyzer engineered for comprehensive signal analysis and generation across DC to 250 kHz. Built with integrated PC and Windows-based interface, it delivers precise measurements critical to audio product development, quality assurance, and system integration. The instrument supports analog and digital audio interfaces with selectable analyzer bandwidth options of 22 kHz, 40/80 kHz, or 250 kHz, and operates at sampling rates up to 400 kHz.
