Microwave Network Analyzers - A Discussion of Verification Methods
Ronald A. Ginley
Verification of Vector Network Analyzers (VNAs) is very important to the measurement process as well as to establish confidence in the uncertainty of the system. This paper presents a basic discussion about VNA verification including what verification is, check standard selection, and different verification methods. Verification methods explored include: quick check, check standards, calibration at higher-level laboratories, interlaboratory comparisons, error separation, calibration comparison, VNA system comparison, and traveling verification kits.
