MT Get Complex IQ Component (G Dataflow)
Extracts the desired component from the IQ (complex) in parameter.
I, Q, magnitude, and phase data are available for extraction from the IQ (complex) in parameter. This node returns a complex envelope in the CE component parameter that contains the t0, dt, and Y values for the chosen component.
IQ data in
The baseband (downconverted) time-domain data.
t0
The trigger (start) time of the acquired signal.
Default: 0.0
dt
Time interval between data points in the acquired signal.
Default: 1.0
Y
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
The complex envelope data component to extract from the complex envelope contained in the IQ Data (complex) in parameter.
| Name | Description |
|---|---|
| I | Extracts the in-phase component. |
| Q | Extracts the quadrature component. |
| Magnitude | Extracts the magnitude of signal. |
| Phase | Extracts the phase of the signal. |
Default: I
error in
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: no error
reset?
A Boolean that determines whether initialization of an internal node state tracks the ending phase.
| TRUE | The node clears the state information about each call. |
| FALSE | The node uses the final phase from the previous call as the starting phase for the next call, ensuring phase continuity between calls. |
Default: FALSE
IQ data out
The baseband (downconverted) time-domain data. This node does not modify this data, so this parameter is identical to the IQ data in parameter.
t0
The trigger (start) time of the acquired signal.
dt
Time interval between data points in the acquired signal. The I/Q sampling rate is the reciprocal of this value.
Y
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
The complex envelope data component selected in the component choice parameter. Wire this parameter to a LabVIEW waveform graph to display the selected component as a function of time.
