Abstract :
Typically, power sensors are calibrated for input reflection coefficient, calibration efficiency factor and linearity. Some new power sensors also need absolute power calibration. Multiple systems are used to measure each of the parameters. With an appropriately configured VNA, all the measurements can be performed with a single connection and set up. This paper shows how it is done and expected uncertainties.
