What is SIGVIEW?

SIGVIEW is real-time and offline signal analysis software package with wide range of powerful signal analysis tools, statistics functions and a comprehensive visualization system. SIGVIEW is highly customizable and flexible but does not require any programming know-how.
Concept

With its unique user interface and philosophy, SIGVIEW gives you the absolute freedom to combine different signal analysis methods in any possible way - there are almost no artificial rules and limitations. Once you get the basics, everything else in SIGVIEW follows the same logical pattern.
Licensing

SIGVIEW is distributed as shareware - you can download a completely functional version and use it for 21 days to find out if it suits your needs. If you decide to use SIGVIEW after that period, you will have to purchase a license. The license key will unlock the time-limited trial version and convert it into a fully-functional licensed software.

Features
                    
  • Support for wide range of data acquisition devices, from common sound cards to professional DAQ devices. Various options for triggering, decimation and file-logging are included. The following device types are supported:                        
    • NIDAQmx compatible DAQ devices from National Instruments®  (voltage input)
    • Measurement Computing® DAQ devices (12/16/24-bit voltage input)
    • LabJack® U3 and U6 USB DAQ devices (voltage input)
    • Microsoft Windows® compatible sound cards (DirectSound and ASIO driver models are supported)
  • Real time data display, signal analysis and control. You can work with live signals and observe results immediately.
  • Import and export of signal files in numerous formats: WAV, MP3, ASCII, WMA, AU, AIFF, SND, 8/16/32-bit binary files, EDF...
  • Optimized FFT algorithm with fine parameter tuning and various pre and postprocessing options: windowing, zero-padding, power spectrum and PSD, automatic averaging, test for spectral peaks integrity,...
  • Spectrogram and Time-FFT functions with powerful graphical display solutions
  • Dual channel (cross-spectral) analysis (cross spectrum, coherence, cross corelation,...)
  • Signal filtering (Bandstop, Bandpass, Lowpass, Highpass)
  • Real-time arithmetics on signals (subtract, multiply, add, scale, normalize...)  
  • Various statistics functions: peak hold, averaging, smoothing, removing linear trend, probability distribution... Analog-style instruments for real-time display of important signal parameters
  • Custom filter curves can be freely defined and applied directly to time-domain signal or to the calculated spectrum
  • Advanced signal display and handling options: unlimited overlays, unlimited number of markers and annotations for each signal, parallel signal display (EEG style), cut/copy/paste signal parts, unlimited zoom levels, VCR-style commands for audio playing,...
  • Signal generator including sine signal, white and pink noise, step signal, sweep signal,...
  • Graphical block diagram environment improves productivity when working with complex analysis systems
  • Custom tools and workspaces can be created and later reused or exchanged with other SIGVIEW users
  • Various command-line options for automation and remote control from external applications or from simple batch files
  • No artificial or license-based limitations: million points FFTs can easily be calculated; dozens of signals can be combined and analyzed at the same time.
  • Field-proven by thousands of satisfied users. See our Reference list for some examples.

Why SIGVIEW?

  • Powerful: Wide range of functions for spectral and cross-spectral analysis, statistics, filtering, exquisite graphical solutions,... everything in one package at one price.
  • Real time: There is no difference between working with live signals in real-time and working with signal files. Start researching with your sound card and continue with professional DAQ devices.
  • Fast: Highly optimized FFT algorithm and 2D/3D graphics
  • Looks good: SIGVIEW will make perfect 3D or 2D graphics ready to become part of your conference paper or presentation
  • Optimal performance at optimal price: You get professional tool at shareware price. Most other signal analysis applications cost at least 10-20x more than SIGVIEW. Find out if they are really better...
  • Risk-free: Try before you buy. You have 21 days to try a fully functional SIGVIEW version to see if that is exactly what you need.
  • Customizable: SIGVIEW can be regarded as a template for more specialized applications. If you need a new analysis option, new design, support for your file formats or data acquisition devices, just talk to us. Customized SIGVIEW versions can be ordered at very affordable price.
