Overview

This VBA macro performs the 2/3/4 port TRL calibration for any selected port. The TRL calibration provides accuracy equivalent to full 2/3/4/ port calibration using short, open, load, and thru (SOLT) standards.

To perform the TRL calibration, you need to prepare thru, reflection (open or short), and line standards. The thru and line must have the same reference impedance Z0 and the same transfer constant (same material).
