Data Evaluation

Overview

• A&D now offers a professional data evaluation package to complement our testing tools– We have partnered to supply the commercial

package Uniplot

• A&D has worked with Uniplot to ensure the tools work together– Uniplot now supports A&D file formats– Integrations are added to enable seamless

interoperability

The Package

• There is now an A&D OEM version of Uniplot– Purchased from A&D only– Includes all content to work with A&D tools– Includes the full functionality of Uniplot

• In addition to the tool, A&D fully supports Uniplot as a standard tool– Helpdesk– Training– Engineering services

Data Evaluation

• Uniplot is the A&D solution for data evaluation, this includes:– Reports– Interactive analysis– Mining data from iCentral server

• Uniplot runs on:– iTest PC – produces report for operator– Engineers PC – reports, interactive analysis,

data mining– FUTURE: LabReporter

Configurable Reports

• Reports are parameterized to adapt to customer test:– Example Heavy Duty Emissions Certification:
