Use Track And Timing Functions To Analyze PWM Signals.LeCroy Applications Brief No. LAB_WM421 Modulation Analysis - PWM Use Track And Timing Functions To Analyze PWM Signals Pulse Width Modulation (PWM) is commonly used in power sup- plies and industrial control sys- tems. It has the advantage of ef- ficiently driving switched mode devices at a fixed frequency. LeCroy’s Jitter and Timing Analysis 2 (JTA2) analysis op- tion contains a number of func- tions and parameters to extract the underlying modulation sig- nal, making it possible to assess correct tracking and linearity in PWM regulators/controllers. The top trace in Figure 1 (Ch2) contains 50 ms of an acquired PWM waveform. Trace F3 is the Track function of the Figure 1 Analyzing a PWM waveform using the track of the width@level p……
