niwlan analysis session specifies the niWLAN analysis session refnum.

active channel specifies the active channel string.

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

niwlan analysis session out passes a reference from the niWLAN analysis session to the next VI.

Note Close the niWLAN analysis session reference using the niWLANA Close Session VI before the completion of execution to avoid possible memory leak issues.

CFO CCDF trace returns the CCDF measurements on the absolute carrier frequency offsets.

	Min Bin indicates the bin centered at the minimum absolute carrier frequency offset value.
	Bin Size indicates the size of each bin.
	CCDF indicates an array of CCDF values of the absolute carrier frequency offsets.

error out contains error information. This output provides standard error out functionality.
