OPEN/SHORT Response Calibration (Reflection Test)

In OPEN or SHORT response calibration, calibration data are measured by connecting an
OPEN or SHORT standard, respectively, to the desired test port. For frequency response,
these calibrations effectively eliminate the reflection tracking error from the test setup in a
reflection test using that port (Figure 4-2). It is also possible to carry out isolation
calibration with a LOAD standard during OPEN/SHORT response calibration. An
isolation calibration will eliminate the directivity error from the test setup in a reflection
test using that port (Figure 4-3).
