Both REW and WinISD have signal generators you could use, REW having more options.

Since the shutter is opening and closing much quicker you need a lot of light to capture video in high speed. At 240 FPS you need 8 times more light then then minimum you need for regular 30 fps video.
I should note that I was unable to push the driver to its limits as I was power limited, though it was starting to make some decent suspension noise. If the meter was correct at a little over 28v per coil the amp would start to clip, that would be about 200 watts per coil or 400watts total. I am not sure that is correct as I was using an old sony STR-DE915 for power rated 100w/ channel @ 8 ohms.
