Full one-port calibration (SOL) is used for reflection coefficient measurements (S11 or S22). The three calibration standards (SHORT, OPEN, LOAD) are measured (See figure below) in the process of this calibration. Measurement of the three standards allows for acquisition of all the three error terms (Ed, Es, and Er) of a one-port model. Full one-port calibration is a highly accurate method for one-port reflection measurements.
