CITIle Reference
A Three-T erm Cal Set File
This example shows network analyzer 1-P ort cal set le . 1-P ort calibrations compensate for
three error terms , directivity , tracking, and source match. Therefore , there are three data
portions in a 1-P ort cal set CITIle . These three arrays of error correction data are dened by
using three DATA statements , E[1] to E[3] .
When a cal set le is loaded, it must include the original instrument settings for that
calibration. As explained in the Calibration chapter , calibrations are sensitive to certain
instrument settings , known collectively as the \limited instrument state ." Y ou must use the
limited instrument state that was in eect when the calibration was created. T o accomplish
this , the CITIle stores all settings in the limited instrument state . This is why there are so
many #NA statements in the CITIle example below .
