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?

Let me join with my own headaches ;)
1. trigger by video does not work at all. I specialy want to trig on specific line number, but no sync.
2. protocol decoding does not work at all. Trying UART at 9600, and SPI - no success, just "no trigger" or "adjust timebase"
this is with last firmware update. What version is known without these bugs ??

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.

Dear Sir,
What is the system information of your machine? When is the software.

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.

I switch the generator to 50Ω, the amplitude shown by the numbers decreases by 2 times, the real signal does not change, we connect a 50Ω resistor and see what it shows correctly. We begin to raise the voltage of the generator with a handle, it grows in numbers, and the real range immediately drops by 2 times. Turn off the 50Ω button on the generator, turn off / turn on the generator, it shows real numbers and full swing.

It is necessary and sufficient that when the load is switched to 50 Ω, the generator voltage indicator shows 2 times less, and when the generator load is switched to 1MΩ, it shows the real voltage. Everything.
