Abstract
Some important vector network analyser (VNA) calibration procedures, such as thru-reflect-line (TRL), are not amenable to propagation of measurement uncertainty by conventional methods, because the equations involved do not explicitly refer to estimates of calibration standards used. However, the sensitivity of calibration constants to those estimates can be found by relating changes in standard values to changes in VNA readings. This is easily implemented with new algorithmic methods of uncertainty propagation.
