--- Quote from: TopQuark on April 13, 2024, 01:46:46 pm ---I found one trick that made graphics rendering more consistent is to feed a fast waveform (e.g. 1MHz sine wave) to a spare input as the trigger source, to force as fast an update rate as possible on the scope. This ensures as little dead time as possible between triggers, and that the waveform update rate is consistent. Also, this avoids situations where the graphics is just a dot, or a vertical/horizontal line, the waveform does not update unless in auto trigger mode. The improvement in graphics quality from this arrangement kind of makes sense, as XY mode on analog scopes is just a completely continuous vector plot without triggers. So by actively forcing the waveform acquisition to trigger unconditionally with as little dead time as possible, the graphics rendering would be the closest to what an analog scope could produce. By feeding a 1MHz signal from the scope built-in AWG to the external trigger input, I could achieve 46.9 wfm/s , when the timebase is set to 10k sample memory, 500kSa/s, 2ms/div. The shroom on my screen looks really nice. Side note 1: Listening to the original quality audio tracks with earphones is a trippy experience, the data modulation audio pulses hits your ears like no other music. I imagine this is what the life of a RF demodulator sounds like. Side note 2: A discussion on analog graphics rendering capabilities of digital oscilloscopes, what a time to be alive. ::) --- End quote --- This makes a lot of sense, i found i get better results with trigger set to "none" on my AD2, and that's what i used for potential is forever! have you tried with trigger set to auto but placed at a higher voltage than any of the two channels will ever reach? |

Thanks for starting this thread. Some of these are very impressive. --- Quote ---I found one trick that made graphics rendering more consistent is to feed a fast waveform (e.g. 1MHz sine wave) to a spare input as the trigger source, to force as fast an update rate as possible on the scope. --- End quote --- Maybe there is a better way to detect the update rate (of the screen). Manufactures seem to post the number of sweeps or waveforms they can store, but not how fast they can display the data. |

It was suggested that triggering from a 3rd channel might help with performance. I setup CH3 with a 1MHz sine wave, and set the edge trigger to that channel. I activated and deactivated my AWG and saw no change whatsoever with the performance. Triggering in general hasn't shown to have an effect here IME. At least that's how it is with my scope. 🤷 |

I did another quick test showing object frequency from OsciStudio. I went from A1 - A4, in sequency that's 55Hz to 110Hz to 220Hz to 440Hz: |
