3-port TRL calibration

3-port TRL calibration
The 3-port TRL calibration function lets you measure calibration data by connecting thru,
reflection (open or short), line, or match calibration standards to (between) 3 desired test
ports. This calibration provides the most accurate measurement for non-coaxial parts, using
27 error terms in total for calibration in the same way as full 3-port calibration.
NOTE
This function is available with firmware version A.06.00 or later. For firmware version
A.06.00 or earlier, you can use VBA macros to define/save calibration kits and execute
calibration. For more information, see Appendix A, "Manual Changes," on page 583.
Before executing TRL calibration, you need to modify the calibration kit definition you use
(or create a new one). For more information, see "Changing the Calibration Kit Definition"
on page 181.
