That is the point, roll mode never clears the screen. There are never any breaks. No matter whether you change time base, Volt/div or whatever.
Roll mode also has single shot triggering.
Picoscope does not have roll mode - so far. That´s it.
That is no problem. Let´s hope it will be implemented by next software update.
But it is a problem if people insist on their wrong opinion, attack others and are not willing to accept the facts.
I really don´t understand why you are so obsessed by that topic.
What do you mean by "Tek" oscilloscope?
Tektronix has a real roll mode, no clearing screen.
Tekway does not have roll mode, it is clearing screen.
My Rohde & Schwarz has roll mode, and so does Keysight.
And even some cheap handheld scopes and some crappy Hantek rigs (a jerky one, but it is roll mode).
I really wonder why no one talks about the other bugs shown in the video on
http://www.afug-info.deIt took some time, but I tested my picoscope according to that video and I regret but it is true, all bugs can be confirmed.
I hope for a speedy software update and that is what we all should do.
