After a hiatus, I've come back to Network Analyzers, and have a simple question.  

I was reading the datasheet for the E8364C PNA, and ran into two kinds of error specification, Uncertainty and Tracking, but no explanation of these terms.  

My guess is that Uncertainty is the error compared to a recognized standard, and Tracking is another word for repeatability.  

Is this correct?

I assume that this is well explained in an app note.  Which app note would that be?
