Pulse Width Modulation (PWM) Generation with U1252A DMM
Application Notes
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 Technologies, Inc. U1252B handheld digital multimeter (DMM), with a built-in programmable square wave generator, can be used to create PWM signals.
