A testing device for a network analyzer is characterized in that a signal output by an output end of the network analyzer is divided into two paths of signals through a power divider, one path of signal is transmitted to a power meter through a first channel, the other path of signal is transmitted to a receiving end of the network analyzer through a second channel, and an amplifier is connected to the second channel through a change-over switch module. The change-over switch module is used for controlling and switching whether the amplifier is connected to the second channel, and the signal processor obtains S parameter error values of signals received by the receiving end of the network analyzer by controlling the change-over switch module when the amplifier is connected to the second channel. And acquiring an S parameter error value of a receiving signal received by the receiving end of the network analyzer when the amplifier bypasses the second channel, thereby acquiring a test error curve of the network analyzer, and realizing the test of the dynamic precision of the receiving end of the network analyzer.
Description
technical field [0001] The invention relates to the technical field of network analyzers, in particular to a testing device for network analyzers. Background technique [0002] A network analyzer is a comprehensive microwave measuring instrument that can scan and measure within a wide frequency band to determine network parameters. Dynamic accuracy is an important index parameter of network analyzers, which measures the ability of the receiving end of the network analyzer to measure the signal amplitude and phase when the input power dynamic range changes. Good dynamic accuracy of the receiving end is achieved by the network analyzer. Guarantee of stable and accurate measurement. [0003] At present, there are very few patent documents on the dynamic accuracy of the receiving end of the network analyzer. Therefore, there is a lack of a device capable of testing the dynamic accuracy of the receiving end of the network analyzer. Contents of the invention [0004] The techn...
