Digital twin technology uses data such as physical models, sensors, and operation history to map objects in the physical world in virtual space, thereby performing real-time and dynamic simulation. During the product development and design phase, engineers do not need to make modifications to real objects, but instead conduct experiments on "twins", thereby improving R&D efficiency and saving costs. RF System Explorer and D
PD Explorer are system design and verification tools specially created by Keysight for RF circuit designers. They extract RF system-level digital twin parameters based on the ADS design environment.
