Observer Data Analysis Suite is a comprehensive tool for advanced analysis and post-processing of the data obtained with Digitex Systems units for permanent structural monitoring or Ambient Vibration Measurements. Observer Data Analysis Suite provides wide range of powerful signal analysis tools that help the engineers to understand the structures behaviour. Besides the standard processing techniques like time domain analysis, filtering, frequency domain analysis (FFT, PS, PST, SVD), time domain integration (velocity and displacement) Observer also offers advanced features like calculating the Response Spectrum (using different calculation methods), damping ratio for selected channel and frequency and Operational Modal Analysis (OMA) for determining the dynamic characteristics of the structure. Observer Data Analysis Suite also offers animation feature for visualization of the structure's behaviour in 3D at different frequencies for better understanding the natural frequencies and mode shapes of the structure. Advanced reporting feature of the Observer Data Analysis Suite can be used for sharing the structural behaviour of the structure and additional updating and corelating of the Finite Element (FE) model of the structure, design verification and determining the potential problems during and after the construction.
