niRFSA Get Spectral Info for SMT

Returns a cluster containing information about the power spectrum NI-RFSA computes that is needed by the Spectral Measurements Toolkit (SMT).

instrument handle identifies your instrument session. instrument handle is obtained from the niRFSA Initialize or the niRFSA Initialize With Options VIs and identifies a particular instrument session.

error in (no error) describes error conditions that occur before this VI runs.

	status is TRUE (X) if an error occurred before this VI ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI ran. The default is FALSE.
	code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning. The default is an empty string.

instrument handle out passes a reference to your instrument session to the next VI. instrument handle is obtained from the niRFSA Initialize or the niRFSA Initialize With Options VIs and identifies a particular instrument session.

spectral info returns properties of the computed spectrum such as spectrum type, spectrum scale (linear or dB), the window type used by the VI to compute the spectrum, window size, and FFT size. Connect this parameter to subsequent VIs that contain the spectral info parameter. Do not modify the values.

	spectrum type
	linear/dB specifies whether the spectrum scale is linear or in dB.
	window specifies the time-domain window the VI uses.
	window size
	FFT size

error out contains error information. If error in indicates that an error occurred before this VI ran, error out contains the same error information. Otherwise, it describes the error status that this VI produces.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code the error or warning code. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning.
