i could really need the “Realtime-Scan” from 1-100ms. I already contacted BenF for this, but he said post it in the forum, so i did, and now i need you guys to help me to convince him to put this in (it also would’nt be much work i guess ) .
I have to check a signal (square-signal) for single missing parts, that has about 200Hz. With AUTO it takes to long to reload the screen so i would not see those missing parts. Too sad that SCAN only works with 100ms and up.
Ben said to me that the eyes could not follow the wave below 100ms, but i say this is wrong. I can see the swiping of the wave down to 20ms. A realtime sweep of the screen with 10ms/DIV would take about 120ms. Thats like 8 Frames per second which actually less than 12 FPS which makes the eye see a motion. You might have seen those oldstyle Movies where u can see the dirt spots on the film.
I think the SCAN is useful down to 2ms (if the refresh rate of the screen is like 30 FPS). Changes in a not moving signals are easy to see, and i would bet you could see changes of a signal with a refreshrate of 40FPS. At 50ms/DIV it takes like ages to redraw the wave, and this annoyes me really when i want to see how the signal is behaving in realtime!
Is there anyone else that thinks the same?
