These days, modern devices that digital engineers design are highly integrated and complex. Which naturally leads to the need for testing devices with more than four ports. In wireless RF specifically, front-end modules (FEM) for multi-band operation and multi-input, multi-output (MIMO) antennas require multiport characterization for all their components. Testing high-speed digital technologies like HDMI and USB 3.1 can be even more tedious. This need for multiport testing accelerated the development of switch-based solutions for traditional vector network analyzers (VNAs). When switch-based solutions aren't adequate to keep up with multiport testing—the VNA itself was re-imagined and optimized for the task.

Discover the ways a redesigned, multiport VNA, can significantly reduce testing time and deliver highly accurate measurement on multiport devices. Check out the detailed whitepaper provided by Keysight Technologies by clicking the button below.
