I bought the dso2c15 a few days ago When I press the zoom button, the screen freezes.
So after receiving the dso2000 firmware from hantek website this site, and I updated the software to 20210223.00.
Now zooming is fine, but at sampling below 500MSa/s, the trigger only catches half of the screen.
As a result, 1khz is displayed as 2khz. Therefore, it is not possible to measure frequencies below 1MHz.
Frequency and trigger work normally only at 500MSa/s sampling.
So I want to downgrade to the original old version firmware. where can I download it?
Everything seemed to be fine, but all of a sudden the front usb was not recognized.
I thought it was a hardware defect, so I asked hantek service for help,
and when I got a repair program from the person in charge and ran it,
everything was back to normal.
After that, I updated to the latest firmware and now everything works fine.
