Creates an output waveform using a formula string to specify the time function to be used. Example

	offset is the DC offset of the signal. The default is 0.0.
	reset signal, if TRUE, resets the time stamp to zero. The default is FALSE.
	frequency is the frequency of the waveform in units of hertz. The default is 100.
	amplitude is the amplitude of the waveform. The amplitude is also the peak voltage. The default is 1.0.
	formula is the representation used to generate the signal out waveform. The default is sin(w*t)*sin(2*pi(1)*10). The following table lists the defined variable names. f Frequency equal to the frequency input a Amplitude equal to the amplitude input w 2*pi*f n Number of samples generated so far t Number of elapsed seconds fs Sampling frequency equal to sampling infoFs
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	sampling info contains sampling information. Fs is the sampling rate in samples per second. The default is 1000. #s is the number of samples in the waveform. The default is 1000.
	signal out is the generated waveform.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error 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. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
