Inputs/Outputs

  • ccclst.png data —

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

  • cdbl.png t0 —

    t0 specifies the start time of the first sample returned. The timestamp corresponds to the difference in seconds between the first sample returned and the Reference Trigger location. The timestamp is zero if the Reference Trigger has not occurred.

  • cdbl.png dt —

    dt specifies the time interval between data points in the acquired signal. The I/Q data sample rate is the reciprocal of this value.

  • c1dcdb.png Y —

    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 I/Q point, use the equation (I2 + Q2)/2R, where R is the input impedance in ohms (Ω). For RF signal analyzers, R = 50 Ω.

  • cerrcodeclst.png error in —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • icclst.png I —

    I returns the in-phase (I) component of data.

  • idbl.png t0 —

    t0 returns the start time of the first sample returned. The timestamp corresponds to the difference in seconds between the first sample returned and the Reference Trigger location. The timestamp is zero if the Reference Trigger has not occurred.

  • idbl.png dt —

    dt returns the time interval between data points in the acquired signal. The I/Q data sample rate is the reciprocal of this value.

  • i1ddbl.png Y —

    Y returns the in-phase (I) components from the input complex data array.

  • icclst.png Q —

    Q returns the quadrature (Q) component of data.

  • idbl.png t0 —

    t0 returns the start time of the first sample returned. The timestamp corresponds to the difference in seconds between the first sample returned and the Reference Trigger location. The timestamp is zero if the Reference Trigger has not occurred.

  • idbl.png dt —

    dt returns the time interval between data points in the acquired signal. The I/Q data sample rate is the reciprocal of this value.

  • i1ddbl.png Y —

    Y returns the quadrature-phase (Q) components from the input complex data array.

  • ii32.png number of samples —

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

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
