Hello everyone, I have a Hantek DSO1062B problem.
symptoms:
No more than 5V on the screen.
Below 5V I see only the upper part of the signal waveform or it is stretched to the whole screen.
No zero lines on the screen with detachable probes.
Self calibration, stops with 32 step error 0x502.
For both cannons the same symptoms.

Hot to do AD9288. After soldering resistors for LMH6552 (RA01, RA02) AD9288 does not heat up. And there is a zero signal line on the screen.

Voltage on systems tested.
DAC OUT (DAC8551) -> VPP 0.800V is ok?

With disconnected probes:
OFFSET1 -> -1.2V
OFFSET2 -> 2.5V
OFFSET3 -> 1,6V
Is it ok?

Tp501 -> 4,096V is ok.

For OP2-C TLV274C -> 2,5V.

Please advice, and voltage values at control points and offset.

Hi, I recently aquired a Hantek DSO5102P and have been attempting to change the baandwidth to 200MHz.  I can connect via a serial adaptor and get data from the DSO (see attachment). It seems to have an extra ine at the bottom and I can't send any list commands etc.  Can anyone shed any light on what might be happening?
