Takes data for a Smith plot and normalizes it, meaning that the data is scaled relative to a known value.

Inputs/Outputs

  • cdbl.png Zo (50.0) —

    Zo is the characteristic impedance of the system.

  • c1dnclst.png points {r,x} —

    points {r,x} is an array of points, where each point is a cluster containing the r and x values that make up the complex impedance r + jx.

  • cdbl.png r —

    r is the resistance component of the complex impedance.

  • cdbl.png x —

    x is the reactance component of the complex impedance.

  • c1dcdb.png points complex —

    points complex is an array of complex numbers.

  • i1dnclst.png normalized smith points {r,x} —

    normalized smith points {r,x} is an array of clusters of points containing the normalized data. Each cluster contains an r and an x value.

  • idbl.png r —

    r is the resistance component of the complex impedance.

  • idbl.png x —

    x is the reactance component of the complex impedance.

    • You can wire an array of points to this VI, where each point is a cluster of an r and an x value, or you can wire an array of complex data to this VI. The VI detects which data input you wire and uses that input. If you wire both inputs, the VI normalizes the array of points.

    This VI normalizes the data with respect to a specified characteristic impedance, Zo, of the system. Then it returns the resulting data as an array of clusters of points, where each cluster contains an r and an x value. You can wire the normalized smith points output directly to the Smith Plot VI.
