The calibration standards defined by data are set using the table of S-parameters. Each line of the table contains frequency and S-parameters of the calibration standard. For one-port standards the table contains the value of only one parameter — S11, and for two-port standards the table contains the values of all the four parameters — S11, S21, S12, S22.
The table of S-parameters can be filled downloaded from a file of Touchstone format. Files with *.S1P extension are used for one-port standards, and files with *.S2P extension are used for two-port standards.
