2-Port Full Calibration (R3765CG/67CG only)
Calibrates the directivity of two port device forward and inverse direction, source match, load
match, frequency tracking and isolation.
All S parameters of 2-port device can be measured with the highest accuracy.
NOTE: If OPT 14 is used, the 2-port full calibration cannot be performed between TEST PORT3 and
TEST PORT4.
(1)
The following four kinds of standard are needed for the calibration.
•
Open standard
•
Short standard
•
Load standard
*
2 pcs. are needed for the calibration of isolation.
•
Through standard
As the characteristics of both directions, forward and inverse, are needed for the execution
of calibration, if the characteristic of one of the directions are to be measured, the charac-
teristics of both directions are measured.
Therefore, for S21 measurement, the sweeping is performed twice for the measurement of
the forward direction and the inverse direction at the execution of 2-port full calibration.
