Acquiring accurate DC measurements is a common need across many applications, but simply purchasing a highly accurate and sensitive instrument is not enough. This guide shows you how to use a source measure unit (SMU) to perform DC measurements by reviewing instrument fundamentals, how to use SMUs, and examining the features that can help you set up your instrument. The various methods covered in this guide also can help you achieve greater accuracy in your applications requiring DC measurements. When applying these methods to your own measurement setup, remember what kind of error each method is designed to address. This allows you to apply the right solution to the measurement issue you’re experiencing.
