Electronic Calibration of a Vector Network Analyzer (VNA) for Non-Insertable Devices

A characterized multi-state electronic transfer standard (MSETS) in conjunction with an unknown adapter can provide an appropriate connector configuration for the characterization of the non-insertable devices. The connector non-repeatability of the adapter is eliminated because it is characterized after it has been inserted in the circuit and it is never removed from the circuit until the non-insertable calibration is finished. Due to non-removal of the embedded adapter, this procedure is very simple and highly accurate.
