VI to output variable freq. sine wave and synchronous variable phase stobe pulse.

[Bassist]

Has anyone ever developed a VI to put out a variable frequency, variable amplitude sine wave from one analog channel with a short duty cycle pulse from a second channel that is synchronous with the sine wave but has control for varying the phase relative to the sine wave?  I need to be able to strobe an LED and visualize the impact that low frequency sound is having on an experimental setup.

Hi Bassist,

That is a very specific example that you are looking for. I checked and I could not find anything quite that specific. In the meantime, I recommend starting with a basic analog output example and modifying it. I would also like to know what hardware you are using for this application in order to determine if you have the features necessary to perform this task.
