About

SAVA: A Signal Acquisition, Visualization & Analysis software

• Signals, as in analog sensor data

• Acquisition, as in data sampling/capturing/recording

• Visualization, as in plotting raw/processed data

• Analysis, as in live/post data processing

The software is thought as a general purpose, easy to use, data processing/visualization tool. However with a machinery dynamics focus in the build in analysis types.

Capabilities

The software has build in support for National Instruments Daq equipment or it can load external source scripts, for customizable data sources (see Input Sources).

Recording and Playback happens via a custom/open Hdf5 file format, but multiple formats can be imported / exported (see File sources and File formats).

Raw and analysed data can be visualized and inspected in real-time or via playback (see Plots).

Most traditional signal processing methods are available such as trending (Mean, Peak, Min/Max, RMS, Variance, Kurtosis, Skew, MAD) and frequency domain analysis (FFT, FRF).

For machinery/rotor dynamics impact testing, tacho, order tracking, waterfall plots, orbit plots and bode plots are supported.
