The handheld AMMP integrates the SP218 probe and a pocket-sized vector network analyzer (VNA) into a rugged, handheld reflectometer device. This system enables 2-18 GHz measurements of component surfaces and is tethered to a laptop or tablet only by a USB cable instead of RF cables, which are the biggest source of measurement error and failure in many systems. It can be used on curved surfaces as well as flat.
