Error Term Data
The error term descriptions in this section include the following information:
• a table of the error terms
• description and significance of each error term
• measurements affected by each error term
• typical cause of failure for each error term
The same description applies to both the forward (F) and reverse (R) terms.
IMPORTANT
Data are listed here as a convenience only. Detailed instrument specifications
are listed in the embedded help in the network analyzer.
If Error Terms Seem Worse than Expected
To verify that the system still conforms to specifications, perform a system verification.
Refer to
Chapter 3, “Tests and Adjustments” .
