VisAnalyser is a powerful program complex intended to record and analyze signals of different dynamic processes. The sources of signals can be different: the data can come from DAQ devices in real-time or from a recorded file. It is possible to analyze the data acquired with RULA devices or imported from other acquisition systems.

#### Possible Applications

- Viewing the waveform of the recorded signal;
- Spectrum graphs: calculation of spectrum density, RMS or amplitude spectrum;
- Statistical analysis: calculating RMS, median, minimum and maximum values in the preset fragment of time; calculating the absolute acceleration value on 3 axes; calculating standard deviation;
- Signal integration and double-integration, calculating the absolute value and sigma-clipping;
- Arithmetic operations: adding, dividing or multiplying a signal by a signal or a constant, subtracting a signal from a signal or a constant;
- Filtration with FIR or IIR filters. You can specify the filter type: high-pass, low-pass, band-pass, band-stop, and the frequency parameters (cut-off frequencies and attenuation ratio);
- Shock response spectrum;
- Waterfall analysis;
- Data recording;
- Modal analysis.

#### Windows Intergation

VisAnalyser can be installed to any Windows OS, starting from Windows 7 or later. To start work, install the program using installation wizard and run the software.

#### Configurable Software

The software comprises a number of options, which can be flexibly configured to meet the user's requirements. It is also possible to add more options when you are already working with the program.

#### Open API

VisAnalyser provides a set of functions, which can be used in third-party software. Thus, you can create your own applications using the algorithms of VisAnalyser software. RULA provides all the necessary documentation and examples for the API.

#### Data Import and Export

If you want to use an analysis function, which is not implemented in VisAnalyser software, there are two possible solutions:

- export the data into CSV or binary format to view it in Matlab, LabVIEW, etc.;
- implement your own reading program according to open specifications.

### Data Analysis

#### Spectrum Analysis

The user can calculate power spectrum density of the signal, view the RMS and amplitude spectra.

#### Part-Octave Analysis

Using part-octave analysis, you can calculate the octave spectrum with the preset octave part from 1/1 to 1/24 based on FFT calculation or IIR-filters.

#### Statistical Analysis

Using statistical analysis, you can obtain various integrated characteristics of the signal, in particular:

- RMS;
- Mean value;
- Minimum value;
- Median value;
- Maximum value;
- Sigma-clipping value.

#### Editing Files

In VisAnalyser you can cut the relevant fragment from the data file and then save it as another file for subsequent analysis

#### Signal Filtration

Filtering the signals with FIR and IIR filters eliminates the noise component from the signal. The result of filtration, as well as the result of other operations can serve as a source of signal for any type of analysis. FIR and IIR filters are available. The user can specify the cut-off coefficient and attenuation ratio of the filter.

#### Balancing Wizard

A fully functional balancing wizard, which supports one-plane balancing and accepts files of recorded data and values as raw data, makes VisAnalyzer a perfect tool of vibration diagnostics.

#### Balancing Calculator

VisAnalyser has an embedded balancing calculator for vibration diagnostics, which helps to calculate the value and position of the corrective weight.

The calculator supports both setting and removing the corrective weight.

### Online Analysis

Online analysis is the analysis of the data acquired from the analog channels of the acquisition systems in real time. It is possible to analyze data from up to 512 channels from different sources. The following types of analysis are available in this mode:

- Spectrum analysis;
- Part-octave analysis;
- Statistical analysis;
- FIR and IIR filters;
- Waterfall analysis.

#### Data Recording

Online analysis mode has an option of data recording. The maximum duration of the recording is only limited by the PC hard drive capacity.

#### Waterfall Analysis

Waterfall analysis shows the dependency of the signal from frequency and time simultaneously. This type of analysis is used to study the spectrum structure of the signal in time.

#### Complex Analysisg

The analysis results in the online mode can serve as an input signal for other types of analysis, for example, RMS or spectrum calculation.

#### Modal Analysis

Modal analysis is essential for finding resonant frequencies and waveforms of the object under test. The software calculates the magnitude and phase frequency response to obtain resonant frequencies and waveforms, analyzing the reaction of the object under test to some impact.
