-Wave Shapes below the line separator in the menu use the AWGAwaveform or AWGBwaveform array buffers to contain the waveform sample data points. A new data set based on the entered values is generated each time the button is clicked. The Impulse, Trapezoid, U-D Ramp, UU Noise ( uncorrelated uniform distribution ) and UG Noise (uncorrelated gaussian distribution ) buttons are used to build waveform arrays based on user input parameters.+Random "Noise" can be added or superimposed on all but the waveform shapes that are built into (use) the Libsmu library functions (Square, Triangle, Sawtooth, Stairstep). When the selector is set to None no noise is added to the waveform. Uniform distribution or Gaussian distribution random values can be chosen. The amplitude of the added noise can be entered in the Amplitude entry space. The noise is calculated and added to the waveform once when the wave shape is selected and a new set of noise values will be calculated and added each time the waveform parameters ( Min, Max, Freq, etc. ) are changed. To add noise to a DC value, use the UU Noise or UG Noise wave shapes and set the Min and Max value so that they are centered on the desired DC value and are above and below the DC value by the desired noise amplitude.

 The basic shape of the Impulse waveform is shown in figure 10. The Max, Min, Freq, Phase and Duty-Cycle values are used to construct the waveform. The Freq setting determines the Period ( 1/Freq ) or spacing between the pulses. The output starts and ends at a value midway between the Min and Max values. The impulse consists of a positive peak followed by a negative peak. The width of the peaks are equal to (Period * DutyCycle)/ 2. The center of the pulse is delayed by the Phase setting. For example if the phase is set to 180 then the pulse is delayed by ½ the Period (Phase/360).  The basic shape of the Impulse waveform is shown in figure 10.
