True Differential Measurements: Characterization Of Balanced Devices By Rohde & Schwarz GmbH & Co. KG
Differential devices offer advantages like noise immunity, low crosstalk, high integration density, and reduced power consumption. However, they also require special measurement capabilities. There are essentially two different measurement methods available: virtual measurements and true differential measurements. This white paper provides an overview of both the virtual and true differential measurement methods.
