7.5.11 3-Port Full Calibration
This function calibrates the directivity, source matching, load matching, frequency tracking, and
isolation for a 3-port device.
This calibration method can be used only for the R3765CG and R3767CG equipped with OPT11
(built-in 3-port), OPT13 (Impedance: 75
Ω
, built-in 3-port) or OPT14 (4-port test set) individually.
There are two possible combinations for 3-port full calibrations as listed below when using OPT
14 with the R3765CG or R3767CG.
