M980xA

The Keysight M980xA Series is a family of PXIe vector network analyzers (VNAs) designed for RF and microwave measurements. The series covers frequency ranges from 9 kHz up to 53 GHz, with models offering 2, 4, or 6 test ports (2-port models up to 53 GHz, and 2-/4-/6-port models up to 20 GHz). Each module is a fully independent vector network analyzer, and multiple modules can be installed in the same PXI chassis to form a true multiport VNA with up to 50 ports. The M980xA is used for testing passive components, amplifiers, mixers, and frequency converters.^[2]

Vector network analyzers measure the magnitude and phase of transmitted and reflected signals from a device under test, characterizing parameters such as S-parameters, return loss, and insertion loss. The M980xA operates on the PXIe modular instrument platform, with each module containing its own signal source, receiver, and test ports, allowing synchronous measurement of multiple ports with multiport error correction. The modules can be interconnected using specific cable assemblies (e.g., Y1730A series) to extend the port count or to combine with other PXI instruments such as the M983xA. The system applies calibration using mechanical or electronic calibration kits to correct systematic errors, and specifications are defined under controlled temperature and calibration conditions.^[1][2][3]
