Network Analyzers using S4VNA software

Completes the procedure of the full 3-port or 4-port calibration that used 2-port ACM. The calibration type (3-port or 4-port) and port numbers are selected by commands SENS:CORR:COLL:ECAL2:METH:SOLT3 or SENS:CORR:COLL:ECAL2:METH:SOLT4.  Calibration steps must first be performed using a 2-port ACM between different pairs of ports in such a way that there is at least one ACM connection to each port (see SENS:CORR:COLL:ECAL2). Optional THRU connections between other port pairs improve the calibration accuracy (see SENS:CORR:COLL:ECAL2:THRU). At the attempt to complete the calibration before all the needed steps are executed, an error occurs, and the command is ignored.
