MT Add MultiTone (G Dataflow)

Version:
    Last Modified: February 7, 2018

    Generates a multitone waveform, adds it to the complex baseband modulated waveform, and returns a signal-plus-tones waveform. You can use the tones-added signal to test transmitter interference rejection.

    Note  

    The amplitude of the multitone waveform is the sum of the amplitude and reference power values.

    datatype_icon

    input complex waveform

    The modulated complex baseband waveform data.

    datatype_icon

    t0

    Trigger (start) time of the Y array.

    Default: 0.0

    datatype_icon

    dt

    Time interval between data points in the Y array.

    Default: 1.0

    datatype_icon

    Y

    The complex-valued signal-only baseband modulated waveform. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.

    datatype_icon

    tones

    The frequency and amplitude of tones to be generated by this node.

    datatype_icon

    freq

    The tone frequency in hertz (Hz).

    Default: 0 Hz

    datatype_icon

    amplitude

    The tone amplitude in dB, relative to the specified reference power.

    Default: 0 dB

    datatype_icon

    reference power

    The reference power, in dBm, for the amplitude parameter.

    Default: 0

    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

    reset?

    A Boolean that determines whether this node continues tone generation using the previous iteration states.

    TRUE Resets the phase of the generated multitone to 0.
    FALSE Continues the generated multitone phase from the previous iteration.

    Default: TRUE

    datatype_icon

    output complex waveform

    The signal-plus-tones complex baseband waveform data returned by this node.

    datatype_icon

    t0

    Trigger (start) time of the Y array.

    Default: 0

    datatype_icon

    dt

    Time interval between data values in the Y array.

    Default: 1.0

    datatype_icon

    Y

    The complex-valued signal-only baseband modulated waveform. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.

    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

    Web Server: Not supported in VIs that run in a web application
