RF Network Analyzers
If the Analyzer Fails This Test
• If the frequency measured is close to the specification limits (either in or out of
specification), check the time base accuracy of the counter used.
• If the analyzer fails by a significant margin, the master time base probably needs
adjustment. In this case, refer to the “Frequency Accuracy Adjustment” procedure in
Chapter 3 , “Adjustments and Correction Constants.”
•See Chapter 7 , “Source Troubleshooting,” for related troubleshooting information.
