This section provides information about determining the uncertainty of the 
measurements on your network analyzer.
Download the Vector Network Analyzer Uncertainty Calculator
You can download a program from Keysight that provides the measurement 
uncertainty associated with your vector network analyzer measurement and 
ECal module. Go to www.keysight.com/find/na_calculator and follow the 
instructions on the Web site to download the program.
The program uses your Keysight network analyzer model number, your ECal 
module model number, and electrical limits to calculate specific uncertainty 
charts for your network analyzer. The program is Microsoft Windows based and 
uses a Microsoft Excel spreadsheet to calculate, graph, and display uncertainty 
curves.
