Abstract
A network analyzer contains a processing device, at least one signal generator and at least four measuring points. The processing device controls the signal generator and processes measured values picked up from the measuring points. The network analyzer implements several calibration measurements on calibration standards, before it implements measurements on a device under test. The network analyzer implements the calibration measurements using the measuring points. The processing device determines error matrices on the basis of the results of the calibration measurements. The network analyzer implements measurements on the device using simultaneously, exactly three measuring points. The processing device determines measured values in each case of a fourth measuring point on the basis of the calibration measurements and the measured values of the three measuring points. The three measuring points belong to the set of the at least four measuring points, at which the network analyzer implements the calibration measurements.
