Customer Consultation


One Channel of my Hantek IDS01070A S/N 612001429 has a defective OPAMP.
I cannot find the part number to replace the OPAMP.  Could you please tell me the manufacturer part number so I can replace the OPAMP?  Hope to hear from you soon.

Dear Sir, Ma'am,

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.

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.

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.

Please set the probe attenuation coefficient of the software and the probes to ×1, and take a picture to study.

Dear Sir, Ma'am,

  Attached is the screen capture of the IDSO1070A.  The probes and software are set to X1 and to be sure, I tried swapping the probes of the two channels and the result is the same.

Do you have a signal generator?
Please input 1KH/1Vpp square wave to CH1 and CH2 at the same time, and set two channel to 100mV/div.
And upload a picture to study.

Dear Sir, Ma'am,

  Attached is the screen capture of the IDSO1070A connected to a signal generator with 1Khz and 1Vp-pk amplitude.  The two channels in the software are set to 100mV/div
