Welcome to the forum.

An 8 year old video is not representative of today's DSO's and there was a Pt2 as the original didn't cover everything.
Then there are Why Digital Scopes Appear Noisy and others that don't.
Each must be judged on their own merit.

I noticed that I hear a faint audible sound coming from the scope when the time scale is around 10us or smaller. It can be best described as sounding like bugs in the summer night. The sound momentary goes away when I twist the knob to change the v/div and the screen updates. It also completely stops when I press the run/stop button. I have attached a mp3 file with the recorded sound, it is very faint but you can hear it pause momentary as I toggle different buttons. Has anybody else noticed this? I got the scope from amazon, should I exchange it? I recently did the patch to unlock all the features (hopefully I can still exchange it lol) but I did notice the sound before I did all that.

I have a similar experience.

Got mine yesterday.
FW 1.03.0.03 build 2021-10-18
Quite annoying bug:
Added measurements to channel are measuring based only on displayed datapoints but are not dependent on trigger.
Counter on other hand is measuring based on all gathered datapoints even for disabled channel but is dependent on trigger and "Reject noise" setting. For example without noise reject it can show inaccurate frequency.
Unit have tendency to stop registering all user input in Zoom mode. Happened to me twice in few hours of testing.
About point no 17 in the bug list - as per RTFM ;) waveform save in *.wfm format is possible only when source is selected to be Memory. WFM format is not available when saving waveform from Screen.
