How-To Guide: Measuring Pulse-Width Modulated Sources

Pulse-width modulation is a useful method to control the luminance of LED bulbs for lighting and display applications. However, sources with PWM can be difficult to measure accurately.

Pulse-width modulation is a useful method to control the luminance of LED bulbs for lighting and display applications. However, sources with PWM can be difficult to measure accurately. Radiant's application engineering team recently performed a series of tests to determine the most effective way to measure pulse-width modulated sources using a ProMetric® I16 Imaging Colorimeter and TrueTest™ Software.

This How-To Guide outlines the results of the study. In it you'll learn how to adapt measurement parameters.
