3.3 Customization of TRL Cal Kit
Apart from the basic functions of measuring the normal DUT, 3656 Series Vector Network Analyzer can
also provide users with accurate TRL calibration and measurement, particularly suitable for the
measurement under non-coaxial environment, which provides a more accurate solution for users to perform
measurement with non-standard coaxial cable. TRL calibration kit is mainly customized by the users,
therefore the analyzer supports user to modify the calibration kit definition or create customized calibration
kit.
This section introduces the calibration kit customization function of the analyzer, taking the definition of a
set of TRL calibration kit as an example. The TRL standard kits used in this example include OPEN,
THRU, and transmission LINE, with frequency range of transmission LINE being 200MHz-800MHz,
transmission LINE delay being 480ps, OPEN and THRU kits defaulted to be the ideal calibration kits.
Connect the USB keyboard and mouse to the DUT before the test, and create a TRL calibration kit as
follows:
