A differential probe can be used to make single-ended measurements by using its negative polarity input as a ground reference contact. Although a differential probe can be used as a single-ended probe, it is worth examining in more detail how well a differential probe performs in making single-ended measurements. The comparison between single-ended probe and differential probe grounding has already described some of the noise performance advantages of using a differential probe for making single-ended measurements. A more quantitative analysis of the noise rejection performance advantage of a differential probe will now be presented along with a discussion of several other single-ended measurement performance issues that should be considered when using differential probes.
