Actually made a typo, I meant from 200V to 20 uV per division!
and it means that I'm impressed, never seen a scope that can do 200V per division directly. I mean we can get high voltage probes sure, but this can handle it inside it.
As for good or bad, you can't use this for fast signals over 4MHz, but for electricity, power supply stuff and analog audio it should be just fine.
For electronics you can use it as well, I2C for example is 400KHz so it will work with that too, so it will with RS-232 and many other things in electronics.
So what I meant was surprised by the specs, as in bad or good, it has its place. Someone that works on old pinball machines would love to have a scope like that I bet.
