PWM Waveform Generation
Using U1252B DMM
Application Note
Introduction
Square wave is a unique function for many applications such as pulse width modulation (PWM). PWM is
widely used in a variety of measurement and digital control applications. It offers a simple method for digital
control logic to create an analog equivalent. Most of today's microcontrollers have built-in PWM capability
that simplifies the control's implementation. PWM is widely-used in communication systems because the
digital signals are more robust and less vulnerable to noise.
This application note provides an overview of PWM and shows how the feature-packed Keysight Technolo-
gies, Inc. U1252B handheld digital multimeter (DMM), with a built-in programmable square wave generator,
can be used to create PWM signals.
