DSO138 Ceramic capacitors

Post by avnerdee »

I check each component before installing and soldering it.
There are 11 ceramic capacitors suppose to be 100nF but all of them are between 50 and 70nF.
Is it normal and I can proceed with the assembly or should I look for higher value capacitors?
I'll appreciate any help about it.

These caps are for coupling and decoupling. Their values are not critical to the functioning of the oscilloscope. We knew the cap tolerance is large. They are ok for the circuit.
