Because lattice gauge port can only generate RF/Microwave signal, the Electronic Calibration part port currently connected can not be led to
The infomation detections such as mark are crossed, so the reflection parameters of each standard of Electronic Calibration part can only be obtained by lattice gauge.Due to electronics school
Quasi- part is there are Multiple Type, standard are also variant, so the measured value for individually comparing each standard room is infeasible.And to electronics school
The Port detecting of quasi- part occurs before calibration network instrument, so the measuring signal that lattice gauge obtains is uncorrected.It is directly right
There is error than lattice gauge measured value and scaled values.
Since Electronic Calibration part is by calibration, i.e., using the vector network analyzer after TRL calibration to each standard
It measures, inside the Electronic Calibration part of measurement result storage, forms the scaled values of electronic standard.The prior art is, in vector
When network analysis carries out Port detecting to Electronic Calibration part port, impedance conversion process, amendment are carried out using first standard
Then system impedance is compared to by the measured value impedance of Current standards with scaled values impedance.If deviation is in threshold value, then it is assumed that
Present port matching, otherwise, continues to judge lower Single port.
Due to using impedance transformation to be modified the impedance of vector network analyzer, belong to one-dimensional amendment.From vector
From the point of view of the error model of Network Analyzer, single port is corrected using 3 dimensions, including directional error, source matching error, reflection
Tracking error.For modified dimension, the capability for correcting of impedance transformation is limited, after proof of algorithm, the inspection of Electronic Calibration part port
