Abstract

To enable the measurer to easily verify the parameter correction conditions, the correction conditions for the parameters measurable by the measurement device are concurrently displayed on the screen of the measurement device related to the ports used in the parameter measurement. The rows and columns are the receive ports and send ports. The symbol F and the symbol R indicate the type of calibration method applied to the parameters measured by the ports specified in the matrix.
