Many thanks.
I downloaded "dso4kc_func_hantek_dso_dso4202c_20191123.0.up" and performed firmware upgrade, but no improvements. The Pass/Fail Test delivers now 100% Fails. To me it seems like there is a strong internal amplitude modulation of input signal with a quite high frequency. This probably distorts input signal and causes amplitude instability. This is a hypothesis onlu, you will certainly know better what t is and how to resolve the problem. Looking forward to your quick reply.
Kind regards, Sead
