#113937 - LCD is slowly! Responding to: ???'s previous message |

There seems to be a confusion between display update rate and the sampling rate. The mid range DSO update the display at rates of around 10k per second, even if the scope is running in the megahertz range. This is unlike the traditional analog scope.
So the display need not be updated at the sampling rate. What is the turn-on time of a typical LCD? Some hundreds of milliseconds? So, when he uses a LCD screen, then refreshing the display at a rate of even only ten times a second will be too fast. Kai |
