MT Get Complex IQ Component VI

Extracts the desired component from the IQ (complex) in parameter. I, Q, magnitude, and phase data are available for extraction. This VI returns a complex envelope in the CE component parameter that contains the t0, dt, and Y values for the chosen component.

IQ data (complex) in specifies the baseband (downconverted) time-domain data.

	t0 specifies the trigger (start) time of the acquired signal.
	dt specifies the time interval between data points in the acquired signal.
	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.

component choice specifies which complex envelope data component to extract from the complex envelope contained in the IQ Data (complex) in cluster.

Note If you do not request phase data, phase continuity is not preserved.

I (0)	The in-phase component is extracted.
Q (1)	The quadrature component is extracted.
Magnitude (2)	The magnitude of signal is extracted.
Phase (3)	The phase of the signal is extracted.

reset? controls initialization of an internal VI state that tracks the ending phase.

TRUE	Set reset? to TRUE to clear the state information about each call.
FALSE	When reset? is set to FALSE, the final phase from the previous call serves as the starting phase for the next call, ensuring phase continuity between calls. This is the default value.

error in (no error) accepts error information wired from previously called VIs. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.

	status is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.
	code identifies the error or warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.
	source describes the origin of the error or warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.

IQ data (complex) out returns the baseband (downconverted) time-domain data. This VI does not modify this data, so this parameter is identical to the IQ data (complex) in parameter.

	t0 returns the trigger (start) time of the acquired signal.
	dt returns the time interval between data points in the acquired signal. The I/Q sampling rate is the reciprocal of this value.
	Y returns 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.

CE component returns the complex envelope data component selected in the component choice parameter. You can wire this parameter to a LabVIEW Waveform Graph to display the selected component as a function of time.

	t0 returns the trigger (start) time of the acquired signal.
	dt returns time interval between data points in the acquired signal.
	Y returns the data array corresponding to the component selected. This array can contain real (I), imaginary (Q), magnitude, or phase data.

error out passes error or warning information out of a VI to be used by other VIs. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.

	status is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.
	code identifies the error or warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.
	source describes the origin of the error or warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.
