DADiSP® Product Background

About DADiSP


DADiSP (Data Analysis and Display), developed by DSP Development Corporation of Newton, MA, is the first general purpose personal productivity software for scientists and engineers. Through a sophisticated integration of powerful computational and analytical capabilities, DADiSP allows users to depict and manipulate large amounts of data in an interactive, graphical environment.

The Standard


DADiSP has long been considered the standard for data analysis in laboratory automation, data reduction, speech processing, sonar and radar applications, digital signal processing, computer-aided engineering, and other fields. It delivers the power, flexibility, extendibility and ease-of-use that make it applicable to a wide range of technical computing tasks.

The Worksheet Model


DADiSP is a general purpose analytical tool for scientists and engineers much like the spreadsheet is a tool for financial analysts. However, DADiSP replaces the rows-and-columns ledger format with a graphical interface that meets the technical user's needs for interactive visual analysis of large amounts of data. A DADiSP Worksheet consists of a series of windows in which data is displayed and manipulated in a variety of graphical and tabular styles simultaneously, according to the user's requirements and applications. DADiSP users can perform multiple complex operations in one window and view results in other windows.

Analysis Windows


Dozens of windows may be created and viewed on the screen at once, with the ability to zoom in or out of graphs, to scroll, and to overlay graphs as needed. In addition, changes made to a singe window automatically cause dependent windows to recalculate and update. In all cases, the user interacts with the data visually, through the keyboard, a mouse, through user-defined SPL (Series Processing Language) routines and DADiSP command scripts or through existing, application-specific external programs that work seamlessly with DADiSP.

2000+ Functions


The multiple windows allow DADiSP to perform a variety of tasks such as data reduction, pattern recognition, peak analysis, statistical analysis, mathematical analysis, Fourier transforms, convolutions, digital filtering, waterfall plots, three-dimensional plots, and many other operations. There are over 2000 functions available for analysis.

Powerful GUI


Aside from its power and flexibility, one of the main features of DADiSP is its graphical user interface which speeds analysis for the novice user and the experienced "power user" alike. Using a variety of icons, menus, property sheets and dialog boxes, DADiSP guides the user through the needed computational and analytical tools. Also important to users and managers making buying decisions, DADiSP presents a consistent interface across all computing platforms. This simplifies and minimizes training and ensures users that skills learned in one version of DADiSP are readily applicable to any other.

Flexible Data Sources


DADiSP allows users to enter data manually or bring in data sets from a variety of sources including ASCII, CSV, 8-bit byte, 16-bit integer, 32-bit integer, 64-bit integer, IEEE single and double precision floating point files, industry and vendor specific formats or directly from many common data measurement or acquisition devices.

Extendible


With command file, user-definable macro capability, and SPL, DADiSP also provides the flexibility and extendibility needed to customize the software and automate DADiSP sessions for specific applications requirements.

Supported Hardware


DADiSP supports Windows 64-bit and Windows 32-bit operating systems in use at many technical organizations. Classic versions of DADiSP also run under X-Windows Motif on legacy workstations from Sun Microsystems, Hewlett-Packard, IBM, Concurrent, Digital Equipment Corporation, NeXT, and Silicon Graphics.

DSP continually upgrades DADiSP in response to the increased accessibility and demand for powerful and very low-cost PC's and the growing need among technical users for a truly general purpose productivity software package.

Over 25 Years of Experience


Based on more then 25 years of experience serving the technical market, DSP continues to extend existing DADiSP features and add new ones to address an expanding market. Key new features of DADiSP are:


Feature Rich


In addition to these new features, DADiSP offers the ability to capture data from numerous sources, multiple data views, a wide array of mathematical and graphical analysis functions, extensive signal processing features, ActiveX and the DSP Pipeline to run external programs from within DADiSP, textual and graphic annotation of windows, virtually no limits on data size, high speed 64-bit IEEE standard double precision arithmetic, and publication quality hardcopy.

Technical Productivity Tool


Just as Excel serves as a general purpose application for business and financial users, DADiSP offers a robust set of features to serve as a rich and diverse productivity tool for scientists and engineers.

The Market Need


Before DADiSP, there was no single general purpose productivity package for the technical user. Traditional financial spreadsheets were powerful and effective for manipulating numerical data, but required extensive customization to meet users' needs. Designed for general business use, spreadsheets were cumbersome for visual analysis of large data sets.

Technical software applications have been available for PC's, but most packages are designed to perform a very specific task. Like spreadsheets, these packages require extensive customization.

General Purpose Solution


DADiSP fulfills the need for a general purpose software package that is designed specifically for the technical user. Although it can be customized, it does not require customization to get the job done.

Powerful PC's


Another important factor driving this need is the rapid growth of the technical PC market. Prices have fallen while computing power has jumped, making it feasible for many organizations to place high performance PC's on every engineer's desk. General purpose software is needed to allow companies and individuals to reap the full benefit of the competitive advantages provided by this powerful hardware.

Market Tested


DADiSP's market-tested power and flexibility make it an ideal software tool for the high performance PC user in a technical organization.

DADiSP Modules


A number of plug-in modules are available for DADiSP, including:

Distribute Stand-Alone Applications


The DADiSP Application Builder is a component form of DADiSP that allows stand-alone applications to embed DADiSP's analytical and/or graphical functionality with royalty free distribution.

Available Worldwide


DADiSP is available directly from DSP Development or from its worldwide network of distributors including VARs, OEMs, software catalogs and computer and instrumentation companies with whom DSP has cooperative marketing arrangements.
