Audio Analyzer Multichannel and costefficient, for use in the lab and in production


The compact cost-efficient R&S®UPP audio analyzer is designed for system applications. It features low height, and comes without front-panel control elements or integrated display. The instrument can be remote-controlled via LAN, USB or IEC/IEEE bus. In combination with an external monitor, mouse and keyboard, it becomes a manually operable measuring instrument for a lab bench. It has an integrated control PC, and the required software is already installed. Users can start taking measurements right away.


Key Facts


  • Suitable for all interfaces: analog, digital and combined
  • Parallel measurements on up to eight channels
  • Up to 80 kHz bandwidth and 200 kHz sampling rate
  • User-programmable filters for analyzer and generator
  • Compact instrument with integrated PC and low height


All test signals and measurement functions in a single box

  • Generation of a wide variety of analog and – with the
  • R&S®UPP-B2/B4 option – also digital test signals
  • Broad scope of measurements on both analog and – with the R&S®UPP-B2/B4 option – digital interfaces
  • Powerful and even multichannel FFT analysis with resolution down to the mHz range
  • User-programmable filters that can be adapted in seconds to the individual measurement task
  • Integrated control PC; manual operation requires only an external monitor and a mouse and keyboard


Large variety of interfaces in a single instrument

  • Two-, four- or eight-channel analyzer with analog inputs
  • Analog generator outputs (two-channel)
