New toy(?) scope Fnirsi DPOX180H, claimed 180MHz/500MSps (May 2023)

The rising edge of the signal is now better visible,
but I would like it to be even brighter.

Another comment,

If I start setting the time base with the H- button, the display update apparently freezes at 20s/div, even if I press the V+, V-, H+, H- buttons, it does not respond. more precisely, it doesn't respond to anything except the arrows!

If you reach 20s/Div.
Try to set the voltage sensitivity in any direction, it is best if you set it to half where you should hear the relay click.
You will not.
Then you press one of the buttons and it sets all values to the way you pressed the buttons. be it voltage or time value.

I'll have to write to them and have them fix it.

I have seen it once week ago.
Now it disappear. Not sure is it related, but  I updated firmware and format internal disk.

Maybe you can record the issue on video with exact steps to reproduce from scratch and show on video your settings and probe settings in case if it is related.

Just tested this and it happens to me as well. I truly hope they fix bugs like this soon.

I really want to like this oscilloscope. The display is a treat, the menus are also very well organized and close to what you would get on a bench scope (at least closer than other handheld scopes). temp-coloring of the waveform is also a huge thing. Being able to capture parts of a wave to use in the generator is also fantastic, and the bandwidth seems to be pretty high for something of this price range and size. But the bugs are very frustrating (also after playing a lot with the probes I realized that I definitely need to change them. They are extremely bad).

Bugs aside, I really dislike how hard they made it to use the cursors, since they only a delta between vertical and horizontal for both channels (even when the other channel is disabled). I'd like to have X1, X2, Y1 and Y2 values, as well as ΔX and ΔY. Since there's a single timebase the readings of X1, X2 and ΔX don't need to be done "per channel". The Y measurements will of course depend on both the vertical offset of the channel, as well as the scale, so they could either display only the measurements on the currently selected channel (so if you switch to CH2 it would measure on CH2 params) OR, they could add a setting in the "cursors" menu that allows you to select the channel on which the cursor measurements are performed. Alternatively, they could display two small windows, one for CH1 and another one for CH2. That would waste screen space, but it's kinda what they are doing now by showing you measurements of CH2 even when it's not even enabled.
