PathWave System Design (SystemVue) 2022 Update 0.2 is available now!

PathWave System Design 2022 Update 0.2 is a minor update release. It continues the focused effort on RF system modelling excellence, derived from Keysight’s measurement science leadership, and offers powerful connectivity to other enterprise tools, both Keysight and third-party, which drive digital mission engineering design flow.

PathWave System Design strives to make RF system simulation effective for all system engineers, working in RFIC, subassembly or mission / system-of-systems applications. It enables process flows between circuit design, RF system design, baseband design, and hardware verification through platform connectivity. Enhanced features for Aerospace Defense, Cellular, and Wi-Fi system designers are included, as well as updated RF system simulation capabilities.  Phased array analysis is further enhanced, including improved antenna and RF modeling.
