Disclosed are a method and a device for calibrating vector network analyzers, comprising n test ports (10a, 10b, 10c, 10d, 12a, 12b, 12c, 12d), several calibration measurements being taken when several different calibration standards are connected to the test ports (10a, 10b, 10c, 10d, 12a, 12b, 12c, 12d). Several measurements are taken for calibration purposes. In a first method, each additional two-port test network is successively contacted first in a first measurement based on a two-port reference test network by means of a direct connection or a short adapted line that has a known reflection, length, and damping, whereupon all n test ports (10a, 10b, 10c, 10d, 12a, 12b, 12c, 12d) are terminated in a second measurement by means of known input impedances having any transmission characteristics. In a third measurement, all test ports (10a, 10b, 10c, 10d, 12a, 12b, 12c, 12d) are terminated by means of unknown identical, reflecting terminals. |
