MT Add MultiTone VI

Generates a multitone waveform and adds it to the complex baseband modulated waveform, returning 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 specified amplitude and reference power values.

input complex waveform specifies the modulated complex baseband waveform data.

	t0 specifies the trigger (start) time of the Y array. The default is 0.0.
	dt specifies the time interval between data points in the Y array. The default is 1.0.
	Y specifies 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.

tones specifies the frequency and amplitude of tones to be generated.

	freq specifies tone frequency, in hertz. The default is 0.0 Hz.
	amplitude specifies tone amplitude, in dB, relative to the specified reference power. The default is 0.0 dB.

reference power specifies the reference power for the amplitude parameter in dBm. The default is 0.0 dBm.

reset? specifies whether the VI continues tone generation using the previous iteration states. reset? must be set to TRUE whenever you want to reset the phase of the generated multitone to 0. Set this parameter to FALSE to continue the generated multitone phase from the previous iteration. The default is TRUE.

error in (no error) can accept error information wired from previously called VIs. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
	code identifies the error or warning code. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
	source describes the origin of the error or warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

output complex waveform returns the signal-plus-tones complex baseband waveform data.

	t0 returns the trigger (start) time of the Y array.
	dt returns the time between values in the Y array.
	Y returns 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 passes error or warning information out of a VI to be used by other VIs. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
	code is the error or warning code. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
	source describes the origin of the error or warning. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
