Abstract

The embodiment of the invention provides a system error determination method and device of a network analyzer, equipment and a storage medium. The network analyzer comprises a first port and a second port, the network analyzer is connected with the calibration device, the calibration device comprises three variable resistors which are connected in series, and the method comprises the following steps: when resistance values of the three variable resistors are respectively corresponding resistance values, testing the first port through the calibration device to obtain a plurality of first errors of the network analyzer; when the resistance values of the three variable resistors are the corresponding resistance values respectively, testing the second port through the calibration device to obtain a plurality of second errors of the network analyzer; when the resistance values of the three variable resistors are corresponding resistance values, testing the first port and the second port through a calibration device to obtain a plurality of third errors of the network analyzer; and determining a plurality of system errors of the network analyzer according to the plurality of first errors, the plurality of second errors and the plurality of third errors. And the system error of the network analyzer can be accurately determined.

Description

technical field [0001] The present application relates to the technical field of network analyzers, and in particular, to a method, apparatus, device and storage medium for determining a system error of a network analyzer. Background technique [0002] A network analyzer is a comprehensive microwave measurement instrument that can perform sweep measurements in a wide frequency band to determine network parameters. When a network analyzer measures network parameters, systematic errors will occur due to the imperfections of the internal components of the instrument, resulting in low accuracy of network parameter measurement. [0003] In the related art, the accuracy of network parameter measurement is improved by calibrating the network analyzer. Specifically, the network analyzer measures standard components, such as openers, circuit breakers, matched loads, etc., to calculate the system error, and then removes the system error from the measured network parameters to obtain ...
