Copper Mountain Technologies provides metrologically sound, lab grade USB VNAs which support advanced calibration techniques, including TRL calibration. True TRL calibration requires a VNA with 2 dedicated measurement receivers per test port; except for the TR series and Planar 304/1, all 2+ ports CMT instruments have all the necessary receivers and internal architecture required for true TRL calibration. This application note introduces TRL calibration and describes how to configure TRL kit and perform a TRL calibration in the CMT software.
