OROS-OR25
Multichannel Dynamic
Signal Analyzer
by OROS

Software Overview

OR25 is a PC-based modular-measurement platform offering a high-performance and cost-effective 
solution for various and demanding applications. It integrates high-performance and technology able 
to guarantee in all circumstances the precision and the speed of measurement. Thanks to its full 
integration into PC and Windows, it can be easily and logically interfaced to a wide range of 
analysis software packages.
In the field or in the lab measurement, OR25 offers laboratory-quality measurement on a PC board. 
The instrument accuracy is completely independent of the PC model. In a portable PC, OR25 is a 
light-weight and efficient solution for embedded and in the field measurements. In a desktop PC, 
OR25 is a very convenient multichannel dynamic signal analyzer, able to export measurement results 
to other Windows applications, such as spreadsheets, word processors, and post-analysis packages.

Company Background and Contact Information

OROS has been a specialist in signal processing and speech processing since 1985.
We are active in the real-time signal processing in the audio band. Our main works are in speech 
compression and synthesis, telecom (DTMF, modem, tone detection), and metrology (acoustics, 
vibrations, seismics).
We propose:
•	Standard products: DSP boards (TMS320C25 and TMS320C31 PC boards) and software development tools 
(compilers, libraries of algorithms), customizable FFT analyzers for real-time industrial 
applications.
•	Dedicated products: Developed according to custom requirements: feasability, hardware and 
software design, manufacturing.
•	Research: Involvement in several European ESPRIT research projects, theoretical works, and 
real-time implementation of algorithms.
