Full 2-Port Calibration

In full 2-port calibration, calibration data are measured by connecting an OPEN standard, a

SHORT standard, or a LOAD standard to two desired test ports (or a THRU standard

between two ports).This calibration effectively eliminates the directivity error, crosstalk,

source match error, frequency response reflection tracking error, and frequency response

transmission tracking error from the test setup in a transmission or reflection test using

those ports (Figure 4-15). This calibration makes it possible to perform measurements with

the highest possible accuracy. A total of twelve error terms, six each in the forward

direction and the reverse direction, are used in a calibration.
