Vector Network Analyzers (VNAs) are the preferred workhorse for many laboratories when it comes to calibrating and characterizing passive microwave devices like attenuators, power splitters, ...
For a simple one-port vector-network-analyzer (VNA) calibration, only three error terms are needed: directivity (D), source match (S), and reflection tracking (R).
As commercial, military/aerospace, and other communications designs extend into the millimeter wave (mmWave) spectrum, engineers must adapt their testing procedures and require more from instruments ...
