What is MEscope Visual ODS Pro?
MEscope Visual ODS Pro combines all the features of the Visual ODS package with the features of the VES-3600 advanced signal processing option. The Advanced Signal Processing option includes an FFT to analyze data in the time or frequency domain, as well as cut, copy, and paste the waveform and many other signal processing, acoustic analysis, and Multiple Input, Multiple Output (MIMO) features.

Advanced Signal Processing
- SIMULTANEOUS FFT and IFFT in all measurements in a data block. The FFT will transform any number of samples and is not restricted to a power of 2
- Integration and differentiation of time or frequency signals
- Cut, copy, and paste time or frequency signals
- DC removal of time or frequency signals
- Sort and select waveforms
- Slot and band windows to remove unwanted data from time or frequency waveforms
- Exponential power and windows to remove noise and leakage from impulse response measurements
- A flat top window for precise narrowband signal amplitudes
- A Hanning window to minimize the effects of leakage on frequency spectra
- Calculation of Fourier Spectra, Auto Spectra, PSDs and ODS FRFs from operational data in the time domain
- Signal processing includes Rectangular, Hanning or Flat Top time domain windows, peak shooting, linear or average wait spectrum, and overlay processing
- Visual MEscope ODS Pro can be calculated from automatic and cross-spectrums or automatic transmissibility and reference spectra
- Order-tracked ODSs can be displayed directly from multichannel request-tracked response data
- Mathematical Block functions include complex scale, addition, subtraction, multiplication, division, conjugation, and more
- Conversion of units and scale between Linear (RMS) and Power (MS)
- Measurement scale between peak, peak to peak and RMS
- Waveform statistics (minimum, maximum, mean square, RMS, variation, standard deviation, absolute deviation, power, linear power, crest factor, distortion, curtose)
MEscope Visual Shape Processing ODS Pro
- Integration and differentiation of forms
- Cut, copy and paste in a way
- Sort and select shape shapes and components (DOFs)
- Calculates a shape product to find nodais points and lines between all shapes
- Acoustic intensity, sound pressure level (SPL), sound power, and octave or narrowband measurement ODSs can also be calculated and displayed in animation. Acoustic vibro data (acoustics and vibration) can be displayed in the same structure model, thus allowing you to correlate surface vibration with acoustic field measurements.
MEscope Visual ODS Pro Acoustics
- Animated display of acoustic vibro data (acoustic and vibratory)
- 1/1, 1/3, 1/12, 1/24 octave band measurements are displayed in bar chart format
- Magnitudes can be displayed in Linear reference units, Log, dB, dB
- Acoustic intensity is calculated from cross-spectrums or time waveforms
- The sound power through a surface is calculated from the acoustic intensity
- The narrow band can be converted into octave band measurements
- Weighting A, B and C can be applied to narrowband or octave measurements
- Noise sources can be sorted in a bar chart based on overall percentage, dB, or watts.
- Measurements can be calibrated by tone, using magnitude and tone phase
- The VT-420 also includes advanced processing capabilities for calculating multiple inputs, multiple outputs, or MIMO FRFs.
- Multiple forced responses. Multiple wave forms of time or frequency outputs are calculated from various input wave forms of time or frequency
- Analysis of the path of strength. Multiple input wave forms of time or frequency are calculated from multiple time or frequency outputs
- MIMO FRFs. FRFs are calculated from various wave forms of input and output time acquired simultaneously. Multiple and partial coherence can also be calculated with MIMO FRFs
MIMO Modeling and Simulation with MEscope Visual ODS Pro
- MIMO Forced Response: Calculates multiple response time or frequency waveforms (outputs) caused by multiple excitation forces (inputs), using FRFs or mode shapes to model system dynamics
- Forced Response Sinusoidal MIMO. Calculates and displays response shapes (output) caused by multiple sine excitation forces (input), using FRFs or mode shapes to model system dynamics
- MIMO strength path analysis. Calculates multiple excitation force time or frequency waveforms of multiple responses (outputs), using FRFs or mode shapes to model system dynamics
- MIMO FRFs (transfer functions). These frequency functions can be calculated from multiple wave forms of excitation (input) and response (output) time, using rectangular or Hanning time domain windows, trigger, linear, or average peak retention spectrum, and overlay processing
- Multiple and partial coherences. These frequency functions can also be calculated together with MIMO FRFs. Multiple Coherence measures the overall contribution of all measured excitation forces (inputs) for each measured response (output) for each frequency. Partial Coherence measured the contribution of each measured excitation force (input) to each measured response (output) for each frequency.
- MIMO FRFs (transfer functions) can be calculated from multi-channel and automatic frequency spectra
