The Rohde & Schwarz UPP200 is a compact audio analyzer engineered for production and laboratory applications, delivering high-precision multichannel measurements with integrated processing. Built around an onboard PC, the instrument performs autonomous audio testing—including limit checks and signal-to-noise ratio measurements—without external controllers. It supports parallel analysis across up to eight channels; cascading multiple units enables simultaneous measurement on up to 48 channels. The UPP200 accepts remote control via LAN, USB, or IEC/IEEE bus, and can be operated manually with external peripherals for flexible bench deployment.
