Utility key test passesSoftware reloaded but no difference
Yes, these new series of oscilloscopes has known serious freeze and lockup problems. The somewhat good news is that it seems to be caused for very bug firmware, therefor, it could be fixed by Hantek, if they want.
Which is you software and firmware version? (check the Sys Info page in your oscilloscope). Hantek has released already some updates and, apparently, some versions are more stable than others.
There's a long thread on EEVblog discussing the problems, possible solutions, hacks, etc. for these oscilloscopes: https://www.eevblog.com/forum/testgear/new-hantek-dso2x1x-models/
Others also reported the noise inject in both channels, it's probably from the PSU and is caused by the lack of shielding.
But we are still waiting for a definitive solution from Hantek.
Please send the system information to our email(support@hantek.com) to study.
