Abstract

We develop a new calibration technique for measuring the correction factor of a calorimeter with a vector network analyzer. Based on a wave-parameter formulation, we develop analytic formulas for the correction-factor ($g$) and effective-efficiency ($\eta$). This allows us to calibrate both the calorimeter and the thermistor mount in a single step. This greatly reduces the number of physical parameters involved in calibration processes while tracking correlated uncertainty.
