Fabricating and Using a PCB-Based TRL Pattern with a Copper Mountain VNA

Copper Mountain Technologies (CMT) 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 whitepaper introduces TRL calibration and describes how to configure TRL kit and perform a TRL calibration in the CMT software.
