I am using Labview 6.0.2 Base version, without Sine Waveform.vi (I have Simple Sine waveform, and Sine wave) but these functions are not the same as Sine Waveform.vi. When I try to open any virtual function generator it calls for this waveform which I don't have. I need a continuous sin wave that still maintains it's shape at 400 Hz. I have made a continous wave using a buffer and for loop, but it looks more like a sawtooth wave. Can somebody help me?
