What is SIGVIEW?
SIGVIEW is a real-time and offline signal analysis software package with a 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.
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.
SIGVIEW is distributed as shareware - you can download a completely functional trial version and use it for 21 days to find out if it suits your needs. If you wish to continue using SIGVIEW after your trial period has finished, 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.
- Support for a 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, IEPE velocity/force/acceleration)
- Measurement Computing® DAQ devices (12/16/24-bit voltage input)
- LabJack® U3/U6/T4/T7 USB/Network DAQ devices (voltage input)
- Microsoft Windows® compatible sound cards (DirectSound and ASIO drivers 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
- Order Analysis functions (forward and inverse transformations)
- Dual channel (cross-spectral) analysis (cross spectrum, coherence, cross correlation...)
- Signal filtering (Bandstop, Bandpass, Lowpass, Highpass)
- 3D signal filter for a free selection of filter time, frequency and amplitude properties
- Real-time arithmetic 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, audio playback...
- Signal generator including sine, white and pink noise, step, sweep...
- 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: FFTs can easily be calculated from millions of samples; 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.
