Dear Sir, Ma'am,
The source of the square wave is from the built in square wave of the scope for the probe compensation. Both channels are connected to the built in square wave source.
Attached is a screen capture of the IDSO1070A.

Sorry, I don't understand what you mean.
What's wrong with your oscilloscope? Cause you to suspect OPAMP's problem.
Where does the square signal in the picture come from?
Please use the oscilloscope to test the built-in square wave of the oscilloscope and upload the picture to study.
Here are the pictures of the Hantek IDSO1070A screen capture, Waveform using an oscilloscope and another picture where the signal has been probed.
Hope to hear from you soon. Thank you very much for replying. I really need to repair my DSO.
