well you beat me to a review about it. trying to learn as much as i can with electronics.
One effective way to remove noise is to capture the wave and subtract it but this only works to a maximum of 1M memory, not available for 10M. I noticed that when you have subtract/divide the math works slower, i dont know if this is because of eliminating the noise so the wave seems to vary less or if it is actually slower. It seems that after some use the input noise gets very significant, around 2mV with nothing connected and a -0.2V deviation of voltage values. SPC doesnt fix this but i hope calibration will, i managed to get calibration started by using 2 probes and making sure ground is also connected though i will fully calibrate when i find a way to keep the 2 probes touching without any issue.
If i put the probes on a wooden surface i get other noises too but this isnt a scope issue.
I subtract input wave with probe connected before connecting so that i can see the right waveform and noise coming from what i measure.
The ability to capture 1M worth of wave and perform math with it is quite a nice feature and useful when you are comparing. I wish the scope was heavier, would make it easier to play with all the knobs and buttons.
