Data Viewer

The Data Viewer is optimized for multi-channel dynamic analysis.  Each viewer window provides intelligent menus for editing and analysis operations. 

Key features include:

  • Data import, editing and manipulation functions.

  • Data cursors and Event markers.

  • Axis limits, scale, grid and synchronized zoom options.

  • Plot editing tools for figure customization.

  • Copy, paste, and save figures in common graphics formats (JPEG, PNG, WMF, BMP).

Filtering & Spectral Analysis

sVIEW includes a complete set of spectral analysis and filtering functions for analyzing and manipulating dynamic data.  All functions are optimized for multi-channel data sets.  Option templates simplify analysis and provide a convenient method for standardizing procedures.  

Capabilities include:

  • Digital Filters (LP, HP, BP, Notch, SPL A, B, C).
  • Auto Spectrum, Coherence, and Envelope Functions.
  • Spectrograms (vs. Time & Tracked).

Rolex (Rolex) Sky-Dweller rolex replica uk is to travel around the world the most perfect high-end timepiece, equipped with dual time display, dial design makes the wearer easily read time.

sVIEW provides extensive capabilities for analyzing transient events. These features are particularly well suited for development projects that require the capture and analysis of the dynamic response associated with transient operating events.

Transient Event Analysis features include:
  • Configurable event triggers provide automated selection and identification of transient events.
  • Event data analysis with automatic calculation and display of multiple repeat statistical properties.
  • Data Marker object support for interactive graphical event identification, annotation and data extraction.
  • Process option templates for automating event location and analysis operations.

Time-Frequency Analysis 

Many response signals contain frequency components that vary rapidly with time. Classical spectrum analysis methods are often ineffective in analyzing the frequency content of these signals. sVIEW provides robust joint time-frequency analysis capabilities to assist in the analysis of these time-variant signals.

Time-Frequency Analysis features include:

 
  • Easy to setup and use.

  • Robust time frequency distribution (TFD) algorithm.

  • Extensive TFD graphical display options including image, contour, and rotating 3D surface plots.

  • Optional Time Response and Spectral Function Windows.

Rotating Equipment Analysis

sVIEW provides a comprehensive set of analysis functions to assist in NVH development of rotating equipment. These functions can be used to examine and quantify the order related components of a dynamic response measurement.

Analysis features include:
  • Computed Order Tracking algorithm provides precision analysis results.

  • RPM Tracked Order and Frequency Maps.

  • Multi-channel Order Cuts (Tracks).

  • Multi-channel Frequency Cuts.

  • Tachometer signal to RPM conversions.

Batch Processor

sVIEW includes a powerful Batch Processor for automating and standardizing data analysis procedures. The Batch Processor uses a Point-and-Click interface which makes developing even the most complex data analysis procedures an easy task.
Key features include:
  • Control Panel for creating, editing and viewing process status and parameters.

  • Unlimited data set size. Analyze and entire disk of data with a single click.

  • Hierarchal design for building complex analysis procedures with reusable components.

  • Clipboard support to Cut, Copy, & Paste tasks and operations.
