The "Channel" menu provides all channel settings.
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:

3.1.4 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 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.).
