1)
Or any other 3 known one-port standards. To be used in a guided calibration, the known standards must be declared to be Open,
Short, and Match irrespective of their properties.
2)
Or any other known two-port standard. To be used in a guided calibration, the known standard must be declared to be Through,
irrespective of its properties.
The calibration type must be selected in accordance with the test setup. Select the cali-
bration type for which you can obtain or design the most accurate standards and for
which you can measure the required parameters with best accuracy.
