You are just repeating the same mistake. A single sample converted to an array is still a single sample. If you want a sine wave of a specific amplitude, use the built-in functions to create the entire waveform. If you want a just a voltage value and not a continuous waveform, change the daq assistant.
Thanks for pointing out my mistake. unfortunatly i have to have the wave form with varying amplitude like u see in the screen shot,thats why i used a formula node.Is it a good idea to have an array of values and send one value after other (amplitude values) to the sine waveform generator to generate the same patterns as u see in the attached file ?
There is no screen shot of the waveform you want. Your definition of a sine wave seems to be wrong. What you are generating is asingle point voltage until the inputs to the formula node change. Your division by zero for the loop count is also very wrong.
