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, “Optinking Measurement Results, n will provide a much higher level of accuracy. Figure 6-49 through Figure 6-51 illustrate the improvements that can be made in measurement accuracy by using a more complete calibration routine. Figure 6-49a shows a measurement in log magnitude format with a response calibration only. Figure 6-491, shows the improvement in the same measurement using an SII one-port calibration. Figure 6-50a shows the measurement on a Smith chart with response calibration only, and Figure 6-50b shows the same measurement with an SU one-port calibration.
