DigivibeMX® M20 : Features

Table of Contents

Envelope Alarms

The Envelope Alarms give you the ability to visualize the machine health at first sight according to 4 categories (Velocity, Acceleration, Displacement, Envelope) for each Axis (H, V, A) from each Point of any Machine.

Each Alarm can be configured using a wizard dialog with default parameters and ranges or by setting custom values to meet your own requirements.


Multi-language Support

DigivibeMX® 10 supports more languages. Now it’s available in 4 languages: English, Spanish, Turkish, French and Chinese*.

This new feature allows to download new Language Packages or Update current ones.


Real 3D Waterfall

A waterfall is a time-varying spectral representation (forming a 3D plot) that shows how the spectral density of a signal varies with time. In DigivibeMX M20 you can now enjoy the new Real 3D waterfall tool which can be easily created and rotates when dragging the mouse over the graph like in common 3D software.


3D ODS Analysis

ODS Analysis is now an easy task to do, no more complex drawing interfaces and complex calculations just create your 3D model in your favorite 3D software (3DS Max, Blender, Solid Works etc) and import it into the software in order to make a custom ODS analysis.

Once you have your drawing you only have to open a new route analysis and follow the points one by one to complete the analysis. The phase analysis for 3D simulations will also calculate Coherence between signals as well as Cross Power and Frequency Response to be sure that all recording are coherent. All 3D simulations can be exported to AVI video format and animated GIF images compatible with any operating system.


FFT Spectra

Most of spectral tools in DigivibeMX M20 are based on the FFT algorithm, with a frequency range capable of measuring low speed (1 Hz) up to speeds of 10 kHz. The accuracy of the spectrum varies according to the needs, reaching many millions of resolution lines. Its main purpose is to transform the signal from its time-domain representation to the frequency-domain representation, in order to identify different fenomena such as harmonics, electrical noise, etc.

Machines Database

DigivibeMX M20 allows you to save all your machines features in order to make route analysis. Such information is:

General information

Specific information

  • Name, Area &
  • Measurement Points
  • Coupling joint
  • ISO Class
  • Picture or preloaded image
  • RPM
  • Name and dimensions of each bearing. (+20000 bearings database with all their dimensions)
  • Bearing frequencies
  • Gear frequencies
  • Alarm frequencies

Predictive Analysis Tools

DigivibeMX M20 allows the user to perform predictive analysis of any machine located in the Machines Database. These tools are:

Tendency curves

Cascade spectra

  • Velocity
  • Acceleration
  • Acceleration Envelope
  • Velocity
  • Acceleration
  • Acceleration Envelope

These tools permit to evaluate the evolution of vibrations produced by usual causes such as unbalance and electric noise but also by bearing defects and gearboxes.


Bearings Database

DigivibeMX M20 has an expandable database with information of more than 20000 bearings. The available data for each one is:

General Information

Frequencies calculator

  • Number & Type
  • Internal & External diameter
  • Width
  • Static & Dynamic load rating
  • Fatigue load limit
  • Reference & Limit speed
  • Mass
  • Step diameter
  • Number of rolling elements & its diameters
  • Pitch angle
  • Inner race defect
  • Outer race defect
  • Rolling element defect
  • Rolling element speed
  • Cage defect

Dual Channel Functions

Dual channel analysis has huge advantages, not only because it saves time for the data collection, but also because it allows obtaining information that could not be acquired with a single channel analysis.  For example: Orbits can be drawn and saved also for run down analysis to analyze critical frequencies and their real displacement axis.


  • Orbits
  • Bode Diagram
  • Cross Power Spectrum
  • Frequency Response Function
  • Coherence Function

Advanced Functions

The advanced vibration analysis allows the diagnose of complex failures, relation between points, vibration modes and struture analysis. DigivibeMX M30 has tools to export to universal file formats such as UFF58 and ASCII that may be used in other vibration analysis applications (such as ODS, Operating Deflection Shapes).


A spectrogram is a time-varying spectral representation (forming an image) that shows how the spectral density of a signal varies with time. The horizontal axis represents time, the vertical axis is frequency; a third dimension indicating the amplitude of a particular frequency at a particular time is represented by the colour intensity of each point in the image. It is commonly used to find critical and natural frequencies.

Cross Power Spectrum

Or spectral density is a mathematical function that shows the distribution of the power or energy in a specific frequency range.

Frequency Response Function (FRF)

It’s the quantitative measure of the output spectrum of a system or device in response to a specific stimulus, and it is used to characterize the system’s dynamics.

Coherence Function

When interfering, two waves can add their amplitudes to create a greater amplitude wave than the first 2 (constructive interference) or subtract from each other to create a wave with less amplitude (destructive interference), depending on their relative phase. Two waves are said to be coherent if they have a constant relative phase.

Crest Factor

The crest factor or peak-to-average ratio is a waveform measurement, calculated using the waveform peak amplitude divided by the waveform RMS value. It is used to measure the ratio of the peak power level to the time-averaged power level in an vibration signal.


Automatic Reports

DigivibeMX M20 is able to generate automatic reports in Microsoft Word*, this way it is easy to add necesary information or remove useless data.


  • Parameters: Displacement, Velocity, Acceleration and Acceleration Envelope
  • Time domain graph and spectrum on each parameter
  • Highest points markers
  • Harmonics
  • RMS values
  • Marker values on separate table
*In order to generate those reports, you will need Microsoft Word 2007 or higher IMPORTANT: Starter versions of Microsoft Office do NOT work.


DigivibeMX M20 can export to 3 universal formats: WAV (audio), ASCII and universal file format UFF58.


Is an audio file that can be played with every audio software.


This format produces a file in text format in which all channels are saved in columns. It does not have header and can be set according to the user’s needs.

  • Column Y Channel 1
  • Column X – [Separator]* – Column Y Channel 1
  • Column X – [Separator]* – Column Y Channel 1 – [Separator] * – Column Y Channel 2

* Separator can be defined by the user


Is the most used format for all vibration related softwares, especially by ODS programs. The UFF58 (Universal File Format) is a standard in the experimental dynamics (vibration and acoustic) community, particularly in the modal analysis area.

This format is written in ASCII but has a particular order in its content. It can have many headers so it can contain many signals as well as calculations for the same signals (i.e. APS Auto Power Spectrum, Cross Power Spectrum, etc.)
