Typical Measurement Uncertainty
The following graphs show the typical measurement uncertainty of a
three-port device after full two-port error calibration. The curves utilize
an RSS model for the contribution of residual systematic errors, dynamic
accuracy, and switch repeatability. The isolation values on the curves
represent the isolation that the device presents to the uncorrected port
outside the measurement path.
Figure 4-1 shows the S
21
transmission coefficient (dB) for a three-port
device when the third port is terminated in the inactive port over a
300 kHz to 6 GHz frequency range.
