I recently purchased an DSO5202P oscilloscope.
After some use here are artifacts began to appear.

Sorry my English is bad.

Sir, could you solder?

Yes. I have soldering and rework station.

Please check whether there is pin continuous welding on the four chips.

If not, please replace them. The model is AD9288BSTZRL-40.

Is there a difference, if I put AD9288BSTZ-40 or AD9288BSTZ-100

How to reduce the noise at the input of the oscilloscope. What needs replacing?

Replace the four chips(AD9288BSTZ-40) in the above picture. Also you can use AD9288BSTZ-100 to replace.
