SNA5000A Vector Network Analyzer User Manual 86
It is necessary to manually set the parameter values of L, R, G, and C components if the
circuit model is used.
Checking the
Enable Differential Port Matching
tab means that all ports are matched.
When the frequency range in the S2P file of the imported matching module is less than
the frequency range set by the current interface, the system will extrapolate the S2P file
by default. In other words, all the uncovered low-frequency parameters are replaced by
the first point in the S2P file and all the uncovered high-frequency parameters are
replaced by the last point in the S2P file making the frequency range of the S2P file the
same as the frequency range of the current interface.

Differential and common port impedance conversion operation steps:
The operation of differential port impedance conversion and common port impedance
conversion is similiar to that of port impedance conversion, please refer to the instructions of
the latter.
3.8 Adapter removal / insertion function
Adapters are often used when the network analyzer is used to test the DUT. The vector
network analyzer provides the function of removing and inserting adapters. Before the function
of removing and inserting adapters is enabled, the vector network analyzer needs to carry out
full 2-port calibration.
