DSO2x1x error reports

Zoom window cannot go before trigger position.
When the zoom window is enabled, it can't be moved past the trigger position.
This didn't happen in older firmwares, started around 2021.01.05 update and it's been there since, very annoying bug that nobody is fixing.



Measure statistics
Statistics don't reset after disabling/enabling, you need to go into Type and deselect/select all manually, which is very annoying, you can also see this in "Count" value, which is never resetted unless doing so.

Wave generator
Duty moves in 1% steps, but after rotating fast and reaching 99%, it'll stick to 10% steps, so fine adjustment is lost until manually reaching 0% again.
If offset was modified first, amplitude can be set too high and cause distortion . If amplitude is modified first, modifying the offset works correctly.

So this is Hantek support? Absolutely nothing?

Davidalfa

If it has FW3204, Hantek broke decoding. Try installing FW3202... Everything is in EEVblog.

I update this, none of these issues were fixed with the new update.
The zoom bug is specially limiting.

I don't think it's relevant, happens to everyone, but here you have:

DSO2D10
CN2101029001641
I'm running latest SW.

As I said, the zoom worked correctly in older firmware version up to 2021.01.05, but in these old software versions there were other issues, like poor trigger detection on small pulses.
Newer firmware fixed some bugs, but introduced others, like the zoom problem.

Additionally, I recently found another important bug when trying to capture a single happenning pulse.
Steps to reproduce:
- Set trigger in NORMAL mode, any edge mode, any time division.
- Run a small pulse. The trigger captures and stores the wave because it's in NORMAL mode (Doesn't refresh until next trigger happens)
- I push STOP to stop the sampling and keep the wave in the screen. The indicator becomes red.
- But when removing the probe or conecting anything else, the scope captures another edge and clears the stored wave.

Setting the scope into STOP (Red), does exactly the same thing as Single SEQ, triggers only once, but shouldn't trigger at all.This seems to happen on both old and new software versions.

Also, when pressing run/stop button, often the indicator does strange things, should switch between Red and Green, but very often it goes Orange (Screen shows READY) or Off (Screen shows STOP), seems like something is not updating properly?

Hello? No response and no fix after 4 months?

Found another bug: On wave generator, setting fine offset only goes negative, no matter the rotation direction, only happens in the fine adjustment, not the normal mode.

Channel inversion resets after changing voltage/time divisions:

Waveform generator:
- Low level: After resetting it to 0, any movement reverts it to -100mV.

Measure
- Count in Statistics still not being cleared after disabling it.
    Enabling Statistics again starts with the previous measurement data.
