Abstract:Since the advent of high‐precision noise coefficient measurement system under the cold noise measurement technology of source mismatch error correction ,it has been widely recognized by noise measurement engineer ,its main fea‐ture is to use an impedence tuner to present different(4 ~ 7) source impedence conditions during the section of system self‐cal‐ibration and measurement , thereby reduce or even eliminate origin mismatch error ,improve the accuracy of noise factor measurement .This new measurement system brings trouble to calculation work ,mainly because of more complicated meas‐urement system setup ,considering the mismatch factor of measurement technology and the confidential measurement model technology .A new whole calibration solution is proposed in this paper ,calibration model is set up to solve the calibration problems basically through actual case analysis .
