Testing antennas is essential to maintaining the reliability and performance of wireless communication systems. The VNA test cable is one of the most critical tools in this procedure. A customized cable with a vector network analyzer (VNA) is a VNA test cable, short for Vector Network Analyzer test cable. The electrical performance of microwave and radio frequency (RF) equipment, including antennas, is measured using VNAs. The device under test (DUT) is connected to the VNA via the VNA test cable, which enables precise measurement of characteristics, including return loss, insertion loss, and impedance.
