Oh yeah ? let's see the dot moving across the screen at 1 second per division and demonstrate it principle to students with a battery. I want to see it. A continuous dot moving slowly across the screen. I would bet a case of beer that you can't. Even a raster scan scope can't do it as far as I have seen.

Do you have a really special one ? If not, it will blip blip blip refreshing the display and will not give you the dot moving slowly across the screen. If I am wrong, please supply me the make and model and I will reconsider and possibly retract.



My digital scope is an inexpensive Hantek and it draws a line like a
pencil going across the page. At very low sweep speeds like one second
or even less it makes it eaasy to see a waveform where the 465B with
just the blip going across makes it difficult to tell what the waveform
is.

Still my gripe is the Lissajous paterns will not display very well on
the digital scope.

As in most cases it is good to have a choice between analog and
digital test equipment. Sometimes one seems to suit the situation
better than another.

I don't really need a digital scope, and from what I have read about
them 100 MHz is pretty low for a lot of work. But the Hantek ones do
get good reviews and are fairly cheap. So I might get one just for
fun.
