Hello all! I have a GW Instek PST-3202 DC programmable power source. I want to test the temperature resolution based on voltage fluctuations of my power source. I've begun writing a VI for this, but I don't know how to fluctuate the voltage in a sine wave pattern. I found the Sine Wfm function under Signal Processing, but I don't know how to change the "1D array of double" which is the waveform to "sink of double", which is where I apply the waveform to the voltage of power supply. The VI is attached.
