Overview
The 4-port TRL calibration function lets you measure calibration data by
connecting thru, reflection (open or short), line, or match calibration
standards to (between) 4 test ports. This calibration provides the most
accurate measurement for non-coaxial parts, using 48 error terms model
in total for calibration in the same way as full 4-port calibration.
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.
