Automatic fixture removal (option)
The measurement objects of vector network analyzers involve non-standard connector devices, such as packaged microwave devices and on chip devices. The most significant feature of such devices is that they cannot be directly connected to vector network analyzers. The use of fixtures can connect the tested part to the vector network analyzer, but it also introduces fixture errors. The automatic fixture removal function can extract, store, and embed fixture parameters to obtain the true parameters of the tested part, which is easy to operate and has high accuracy.
When describing fixtures, single end fixtures and differential fixtures can be set, and information such as the number of ports of the fixture can also be selected. To extract fixture parameters, it is necessary to measure the fixture standards. In the standard description interface, the fixture standard includes three types: straight through standard, open circuit standard, and short circuit standard.
Utilize the automatic fixture removal function to extract balance parameters from the tested piece as a whole and perform four port de embedding. The test results show that the transmission parameters can be effectively removed, as well as near-end and far-end crosstalk.
