WMA Test Systems Engineering Toolkity

Test Systems

Engineering Toolkit

Included with each test system is licensing for 2 Engineering Toolkits. The Engineering Toolkit is a suite of applications designed to facilitate the management of a test station.

Test Sequence Development

Minimization of error is key to the design of the WMA Test Sequence development environment. Test Sequences are edited using a graphical tree format editor. The editor takes care of syntax checking and formatting the test sequence to be run. In addition, a powerful scripting language is available for special case programming.

Parameter Maintenance

A parameter editor is available for Test Point, Reject and Limit definition. Test parameters are created using WMA's unique "phrase text" methodology. This allows for a consistent, ordered approach to test record design. All parameter definitions are stored either locally on the test stand in an Access Database, or centrally located on a Server running Oracle or SQLServer (see WMA Data Warehousing page).

I/O Tag Definition

The Tag Definition Editor is used to define I/O points to the WMA Test/Verification system. Each system is supplied with a fixed amount of I/O. For example, a specific type of system may have 32 analog inputs, 9 analog outputs, 3 encoder speed inputs, 3 encoder position inputs, 72 digital outputs, 24 digital inputs, 100 calculated analog inputs, 48 calculated analog outputs. The amounts and types of physical I/O are configured by WMA when the system is sold. The user can use the Tag and Configuration Editor to associate names, ranges, units and calibration information with the physical I/O system. WMA tag configuration allows for easy “characterization” of I/O, examples of this include low pass filtering, polynomial calculation and table interpolation for flow meters.

Test Data Viewer

All test data saved during at test in saved in a test data record. Each test is stored in a file and can be viewed with the Test Data Viewer. This allows your users to quickly scan data collected during a test.

Trace Viewer and Sweep Viewer

The sweep and trace viewer are plotting packages that display sampled I/O in a similar manner. See the I/O Acquisition page for details on the differences between a sweep and a trace. For general purposes, a sweep is a collection of ALL available I/O, plus various system states, a Trace is a collection of selected I/O points and can be saved at a much higher sampling rate.


	Dialog based Test Sequence programming: Forget about remembering cryptic programming language syntax. With the WMA Test Sequence Editor, programming is as simple as filling out information forms. The vast majority of the sequence can be programmed this way. There is still a powerful scripting language for use by die-hard programmers. "Phrase" based test record definition: To begin setting up your test, WMA let's you define all text using a phrase based concept. You type in commonly used phrases ONE time. The rest of the system definitions can then be built from your core phrase definitions. This makes for a clear, orderly and consistent system. Powerful Graphical Engineering Tools: Included with the Engineering Toolkit are the Sweep and Trace viewers. These applications can be indispensable in solving problems and analyzing the signals of your test.
