I’ve noticed that when I change the x-scale the quad stops updating as quickly. Example: I am inputing a 5v 20 HZ sine wave. At 5us if I connect the quad I nearly immediately see the sine wave. However, the time step is too small to see the full cycle. If I change the x scale (orange) from 5 us to 1s it takes about 63 seconds from the time I connect the leads to the time that I see the sine wave. Furthermore during this time It claims that it is refreshing at a whopping 68 fps!
at 100ms it takes 8 seconds.
