摘要
A method and a system for determining system errors and power values for the calibration of a network analyzer (2) containing several test ports (11, . . . , 1i, 1j, . . . , 1n) connects the individual test ports (11, . . . , 1i, 1j, . . . , 1n) in each case sequentially to a short calibration standard (3), to an open calibration standard (4) and to a power detector (5), and measures a signal reflected from the short calibration standard (3), from the open calibration standard (4) and from the power detector (5) in the case of an excitation of the respective test port with a measured excitation signal. Following this, system errors for every test port (11, . . . , 1i, 1j, . . . , 1n) are determined from the respectively measured excitation signal and the respectively measured reflected signals, and, finally, the power value of the excitation signal is measured at least at one test port (11, . . . , 1i, 1j, . . . , 1n) by the power detector (5) connected in each case to this test port (11, . . . , 1i, 1j, . . . , 1n).
