THRU Response Calibration (Transmission Test)

THRU Response Calibration (Transmission Test)
In THRU response calibration, calibration data are measured by connecting a THRU
standard to the desired test port. This calibration effectively eliminates the frequency
response transmission tracking error from the test setup in a transmission test using that
port (Figure 4-6). It is also possible to carry out an isolation calibration using a LOAD
standard in the process of THRU response calibration. An isolation calibration will
eliminate isolation error (crosstalk error) from the test setup in a transmission test using
that port.
