Pod Assignment Dialog

Name:	Lets you name the analyzer.
Type:	Lets you select the timing (asynchronous) sampling mode,
	the state (synchronous) sampling mode, or turn the
	analyzer off.
Pods	Can be dragged-and-dropped under the analyzer to assign
	those channels to the analyzer or can be left unassigned.
