niRFSA Get IQ Components

Separates a complex IQ array into an I array and a corresponding Q array. This utility can be used to conveniently graph I or Q or to perform operations that apply to one or the other component.

Use the pull-down menu to select an instance of this VI.

niRFSA Get IQ Components (Complex Cluster)

Returns the I and Q data as a complex cluster.

data specifies the complex waveform to split into I and Q components.

	t0 specifies the trigger (start) time of the acquired signal.
	dt specifies the time interval between data points in the acquired signal. The IQ data sampling rate is the reciprocal of this value.
	Y specifies the complex-valued time domain data array. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively. To calculate the instantaneous power of a sampled IQ point, use the equation (I ² + Q ²)/2R, where R is the input impedance in ohms. For NI RF signal analyzers, R = 50 ohms.

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.

I returns the I component of the data.

Q returns the Q component of the data.

number of samples returns the number of samples in the input waveform.

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.

niRFSA Get IQ Components (Complex WDT)

Returns the I and Q data as a waveform data type.

data specifies the complex waveform to split into I and Q components.

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.

I returns the I component of the data.

Q returns the Q component of the data.

number of samples returns the number of samples in the input waveform.

	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.
