DADiSP/2002 is the newest release of the engineering spreadsheet designed specifically for technical data analysis.
Top Ten Features
DADiSP/2002 includes a number of exciting new features and enhancements. The majority of these changes and improvements are the direct result of customer requests and interaction. Below is a summary of some of the major enhancements included in DADiSP/2002:
Active Document Server
DADiSP/2002 now supports external Worksheet Documents or .DWK files (DADiSP Worksheet File). DWK files are single file, standalone worksheets that can be saved or opened by DADiSP. In addition, DWK files can be emailed and viewed by anyone running DADiSP/2002 6.0 or higher. DWK files can be displayed directly from the Web by Internet Explorer if DADiSP/2002 6.0 is installed. DADiSP/2002 functions as a full ActiveX Document Server. DADiSP Worksheets can be embedded, manipulated, saved and printed by any ActiveX Container application such as MS Excel or MS Word.
Extended Automation Server
DADiSP/2002 adds several data transfer methods to an already powerful Automation Server environment. DADiSP/2002's dual COM automation support allows both interpreted languages such as Visual Basic and compiled languages like C/C++ to make efficient use of DADiSP as an extremely powerful data analysis engine. Any application supporting Automation can seamlessly connect to DADiSP via standard ActiveX protocols to gain access to over 1000 fast and efficient data analysis routines. DADiSP/2002 also functions as an Automation Client, allowing any COM based Automation Server to be incorporated into the DADiSP environment via SPL, DADiSP's Series Processing Language.
Just in Time Memory Management
DADiSP/2002 employs an optimized memory management scheme to make the most of system memory when processing large or small datasets. Large series are transparently buffered to and from the disk while in memory buffers are sized specifically to the result of the calculation at hand. The maximum buffer size can be customized to take advantage of today's large memory systems. Calculations involving smaller series are automatically compacted to conserve total memory space.
Faster Execution
Combining JIT memory management with code optimizations has resulted in speed improvements of up to 100% for critical signal processing functions such as FFT, SPECTRUM, PSD, CONV and FILTEQ. Additional core routines have been optimized providing increased performance for several other matrix and series manipulation routines.
New Function Wizard
DADiSP/2002 provides a new "Function Wizard" to guide you through the selection of appropriate analysis routines in a simple and natural manner. Functions are easily grouped to form any type of specialized analysis expression or routines can be executed immediately to provide quick and accurate results.
Recursive Window References
Worksheets can optionally include recursive formulae to support the simulation of discrete and analog feedback based systems.
Direct Annotations
Text, legends, line and arrow annotations can be directly manipulated with the mouse. Annotations can be moved, edited or deleted by right clicking or mouse selection. Full text and line annotation properties are configurable by standard dialogs.
Improved Hardcopy
DADiSP/2002 automatically adjusts the Worksheet or Window plot to make maximum use of the printer's graphics capabilities. Plot attributes such as color, margin alignment, borders and text justification can be specified through simple Print Preview dialogs. Print Preview has been enhanced to produce a more realistic rendering of the printed page.
Expanded Documentation
The DADiSP/2002 Function Reference has been significantly expanded and enhanced. Examples from the on-line help files can be cut and pasted directly into a DADiSP Worksheet for immediate evaluation.
SPL Extensions
DADiSP's Series Processing Language, SPL, has been extended to provide variable function arguments, ternary conditional statements, user defined error handlers and optimized loop processing. SPL's C/C++ syntax offers a familiar and clean programming style allowing users to create custom functions and procedures using standard programming techniques.
And Over 100 New Functions
DADiSP/2002 includes over 100 new built-in and SPL routines spanning the areas of matrix and series manipulation, signal processing, math, color, series generation, curve fitting and statistics. DADiSP/2002 now offers over 1000 analysis routines with an intuitive and familiar user interface to provide one of the most comprehensive and easy to use data analysis tools available today.

About DADiSP
DADiSP’s Unique Worksheet Approach Puts an End to Programming
A DADiSP worksheet is comprised of as many analysis windows as you need. Each window can contain either raw data, or data transformed by one of DADiSP’s many analysis functions, shown as a graph or a table. The data and graphs in each DADiSP window can be related through formulas to those in other windows, permitting you to define your own analysis chain without programming. When new data is loaded into the raw data windows, dependent analysis windows automatically recalculate and update, graphically.
DADiSP Brings Your Data to Life... Graphically
DADiSP enables you to look at your data from different points of view. View data as a line graph, a scatter plot, a stick chart, a bar chart, a waterfall plot, a 3-D plot, 4-D colonization or as a basic table of numbers. With DADiSP, you can dynamically scroll, expand or compress your data in any direction. Zoom in on a region of interest, add grids, include scales and engineering units. View your data in whatever colors you wish, overlay one graph with another, and another, and another -- as many overlays as you wish, in as many graph styles as you wish -- the possibilities are endless. Comparing different views of your data couldn’t be easier.
Powerful Enough to Meet All Your Needs
From data input and acquisition, to analysis and display, to reduction and manipulation, to transformation and what-if simulations, to publication-quality output for journals, reports and presentations. DADiSP does it all! With hundreds of powerful functions including mathematics, statistics, Fourier analysis, matrix manipulation, 2-D, 3-D, 4-D and technical graphics, DADiSP has everything you need to do your job simpler, faster and better from start to finish.
Quality Graphics for Presentation Reports
DADiSP gives you high quality graphics and text output on a wide variety of printers and plotters. Text and graphic annotation can be added to any plot to professionalize its presentation and to improve its interpretation. Transfer a DADiSP window or worksheet into your favorite desktop publishing package with DADiSP’s state-of-the-art HPGL and PostScript capabilities.
Completely Customizable and Extendible
DADiSP allows you to create your own analysis functions with SPL and DADiSP Macros, build your own analysis programs with DADiSP Worksheets, run your favorite external programs from the DADiSP environment, and set up your own standard procedures through DADiSP scripts. Create your own pop-up menus with the DADiSP Pop-up Menu Toolkit. With DADiSP you can set up your application once so that others can handle routine tasks for you. Engineers and OEM’s can integrate DADiSP with their own or other hardware and software using ActiveX and SPL.
ActiveX
The Windows version supports ActiveX as a client or server, allowing bidirectional exchange of ASCII or binary data. DADiSP graphs can be inserted into any ActiveX aware application such as Excel or Word.
SPL (Series Processing Language)
A C/C++ like programming language, SPL, is designed to address the special needs, routines, and customization of the engineer, programmer, or OEM. SPL provides all the standard programming facilities including user-defined functions, looping and iteration, conditional statements, array references and variables.
You Choose the Computer
DADiSP supports a wide variety of computers, from workstations to PCs. DADiSP is available under X-Windows Motif on workstations from Sun, Hewlett Packard, IBM, Digital Equipment, NeXT, SGI Concurrent and others. On 386-and 486-based personal computers, the 32-bit native mode DADiSP runs under DOS and Microsoft Windows.
Capture Data From Any Source
DADiSP automatically captures data generated by most laboratory instruments and test and measurement equipment, making your data available for immediate graphic display and analysis. Let DADiSP help you take control of automated test and measurement equipment, or even production equipment. DADiSP is ideal for quality management and factory monitoring applications.
