Full Two-Port Calibration (ES Models Only)
The full two-port calibration, activated by pressing the
softkey within the
FULL 2-PORT
calibrate menu, provides directivity, source match, load match, isolation, and frequency
response vector error-correction, in both forward and reverse directions, for transmission
and reflection measurements of two-port devices. This calibration provides the best
magnitude and phase measurement accuracy for both transmission and reflection
measurements of two-port devices, and requires an S-parameter test set.
In this type of calibration, both forward and reverse measurements must be made. You
have the option of setting the ratio of the number of forward (or reverse) sweeps versus the
number of reverse (or forward) sweeps. To access this function, press
Cal MORE
and enter the number of sweeps desired.

TRL*/LRM* Two-Port Calibration
The TRL*/LRM* two-port calibration, activated by pressing the
TRL*/LRM* 2-PORT
softkey within the calibration menu, provides the ability to make calibrations using the
TRL or LRM method. For more information, refer to
"TRL*/LRM* Calibration (ES Models
Only)" on page
