How Effective Is Accuracy Enhancement?

The uncorrected performance of the analyzer is sufficient for many measurements. However,
the vector accuracy enhancement procedures described in Chapter 5, "Optimizing Measurement
Results," will provide a much higher level of accuracy. Figure 6-50 through Figure 6-52
illustrate the improvements that can be made in measurement accuracy by using a more
complete calibration routine. Figure 6-50a shows a measurement in log magnitude format with
a response calibration only. Figure 6-50b shows the improvement in the same measurement
using an SII one-port calibration. Figure 6-51a shows the measurement on a Smith chart with
response calibration only, and Figure 6-51b shows the same measurement with an SII one-port
calibration.
