After changing the channel settings or selecting another measured quantity, the analyzer needs
some time to initialize the new sweep. This preparation period increases with the number of
points and the number of partial measurements involved. It is visualized by a Preparing Sweep
symbol in the status bar:
All analyzer settings can still be changed during sweep initialization. If necessary, the analyzer
terminates the current initialization and starts a new preparation period. During the first sweep
after a change of the channel settings, an additional red asterisk symbol appears in the status
bar:
Data Flow
The analyzer processes the raw measurement data in a sequence of stages in order to obtain the
displayed trace. The following diagram gives an overview.
The diagram is consists of an upper and a lower part, corresponding to the data processing stages for
the entire channel and for the individual traces. All stages in the diagram are configurable. Note that the
channel data flow for S-parameters (and quantities derived from S-parameters such as impedances,
admittances, stability factors etc.) differs from the channel data flow for wave quantities (and derived
quantities such as ratios, PAE etc.).
All stages are described in detail in Chapter 4, GUI Reference.
