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.

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.

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

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 ...

Sorry, please set the probe attenuation coefficient of the software and the probes to ×1, and take a picture again.

Sorry, there is no.
CC65 has two gears: 1:10 and 1:100, you can use ×10 or ×100 probe coefficient to test.
When calculating, we only need to replace V with A.
