System Overview

The response time function is designed to measure Rise (Ton) and Fall times (Toff) of a blinking target as specified in ISO-13406-2 and VESA FPDM 2.0, section 305-1. Please refer to these documents for the specification requirements and (especially in the FPDM document) notes on the general Response Time Measurement procedure.

     Also included is an automatic gray level transition time measurement.  The response time module will measure an array of gray levels automatically from 1 –256.  The gray levels (drive levels) are programmed in the setup menu and the results displayed graphically as well as in a text file.  Refer to the plot below for a sample data presentation.
