    datatype_icon

    export mode

    Source of the signal and spectrum to export.

    Name Description
    none Uses the fastest computation.
    input signal Exports the input signal only.
    detected signal Exports a single tone.
    residual signal Exports a signal minus the tone.

    Default: none

    datatype_icon

    signal

    The input signal.

    This input supports the following data types:

    • Waveform
    • Complex double-precision, floating-point waveform
    • 1D array of waveforms
    • 1D array of complex double-precision, floating-point waveforms
    datatype_icon

    center frequency

    Center frequency to use in the frequency-domain search for the single tone.

    Default: -1

    datatype_icon

    frequency width

    Frequency width, as a percentage of the sampling rate, for the frequency-domain search for the single tone frequency.

    Default: 5

    datatype_icon

    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error

    datatype_icon

    exported spectrum

    Spectrum of the exported signal.

    datatype_icon

    f0

    Start frequency, in Hz, of the spectrum.

    datatype_icon

    df

    Frequency resolution, in Hz, of the spectrum.

    datatype_icon

    spectrum

    Computed spectrum.

    datatype_icon

    exported signal

    Waveform of the exported signal.

    datatype_icon

    amplitude

    The peak amplitude of the detected tone.

    datatype_icon

    frequency

    The frequency, in hertz, of the detected tone.

    datatype_icon

    phase

    Phase, in degrees, of the detected tone.

    datatype_icon

    error out

    Error information. The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
