Kicking the tires of the NIST microwave uncertainty framework, Part 2

Traceability of a measurement requires two parts: 1) an unbroken chain of measurements and 2) uncertainties for each link of the chain. The NIST Microwave Uncertainty Framework (MUF) can provide both the required parts for a single link in the chain or for multiple links. In Part 1 of this work [1] the scattering-parameter measurement results determined by the MUF were compared to the established technique used at NIST. In this Part 2, the comparison of the uncertainties calculated with the different approaches will be examined and discussed.
