MT IQ to XY Graph (G Dataflow)

Version:
    Last Modified: February 7, 2018

    Formats I/Q data for plotting on an XY graph.

    This node extracts the I and Q data into two arrays (X and Y, respectively), which are bundled into the I vs. Q graph cluster for display on a graph.

    datatype_icon

    IQ data (complex) in

    The baseband (downconverted) time-domain data for representation on the XY graph.

    datatype_icon

    t0

    The trigger (start) time of the acquired signal.

    Default: 0.0

    datatype_icon

    dt

    Time interval between data points in the signal data used to modulate the carrier wave.

    datatype_icon

    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.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    IQ data (complex) out

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

    datatype_icon

    t0

    The trigger (start) time of the acquired signal.

    datatype_icon

    dt

    Time interval between data points in the acquired signal. The I/Q sampling rate is the reciprocal of this value.

    datatype_icon

    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.

    datatype_icon

    I vs. Q graph

    The XY graph indicator. The X axis contains I data and the Y axis contains Q data.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
