| Sep 11, 2020 at 10:18 | comment | added | Chris Stratton | @Lundin there isn't really any fast input here that can vanish before it is seen. They are measuring time while charging and discharging a capacitor. If they are slow to catch that the state has changed that will reduce accuracy but there is no event to miss, since the mode only changes when the software causes it to. | |

| Sep 11, 2020 at 10:08 | comment | added | max_s | @ChrisStratton I used PicoScope 2204A with 1x probe. I added the circuit to the post. | |
| Sep 11, 2020 at 10:02 | comment | added | max_s | @Lundin why do you think that? | |

| Sep 10, 2020 at 23:53 | comment | added | Chris Stratton | Show your circuit and explain how you got your data. Some sort of USB scope? What is your scope's impedance? Did you use a 10x probe? Something like a 1 Meg probe impedance could easily form a voltage divider with a weak current source used for such a thing. | |
