Interactively Visualize, Analyze, and Report Data with DIAdem

Interactively inspecting test data is critical to understanding what takes place during a test. Often you know just by looking at the data if the test is a success or failure. In addition, the ability to overlay several test runs and visually correlate the results gives you the insight necessary to make key decisions. In DIAdem VIEW, you visually inspect your data and draw conclusions by interacting with it in tabular and graphical forms. You use scroll and zoom cursors to identify peaks and features in your data and different cursor options to graphically delete, fit, or copy ranges of data.

Key Data Inspection Features

• Create custom layouts to display data in a way that makes the most sense for you
• Synchronize data with video, 3D charts, sound playback, GPS map displays, and more
• Correlate frames with measurement data, play back in real time, or move cursors interactively to compare data to video images
• Choose from 2D axis systems and data tables for data display
• Use zoom and scroll cursors to interactively inspect data
• Mark areas of data traces for copying, deleting, or curve fitting
• Use graph legends to display cursor-related data point values and data properties
• Create VIEW layouts with unlimited numbers of pages
• Visualize, zoom, scroll, and compare traces
• Save your VIEW layouts for future reuse

DIAdem ANALYSIS offers a wide range of mathematical routines for analyzing your data. DIAdem separates analysis libraries into groups of similar functionality, and each analysis function has its own unique set of parameters. The DIAdem ANALYSIS functions are completely mouse-driven and require no additional scripting to analyze your data. With the formula interpreter, you can enter your own math functions interactively.

Key Data Analysis Features

• Use the formula interpreter for basic scientific functions, including square root, sine, cosine, tangent, absolute value, and MOD
• Use tools for integration, differentiation, summation, peak search, root-mean-square, sorting, and averaging
• Calculate curve fits, running averages, and linear regressions
• Extract statistical information including standard deviation, variance, mean values, and minimum/maximum values
• Create powerful histograms from your data
• Perform fast Fourier transforms (FFTs), coherence, transfer functions, auto and cross correlation, and digital filtering
• Design digital filters, including IIR and FIR filters: Bessel, Butterworth, Chebyshev, lowpass, highpass, bandpass, and bandstop
• Conduct 3D data analysis; integrate, approximate, and interpolate matrices and calculate isolines

To share results with others and collaborate on projects, you must communicate results clearly and concisely. With a drag-and-drop environment tailored for creating engineering and scientific reports, DIAdem REPORT makes it easy to present and share your results with coworkers. With DIAdem, you can create professional, publication-ready reports using a what-you-see-is-what-you-get (WYSIWYG) report editor and export them to the most common report formats. Design publication-quality reports, share your results with coworkers, and document your ideas using DIAdem REPORT. After creating a DIAdem REPORT template, save it to share with coworkers or to use with other data sets.
