My calibration output is very noisy. I think i might have grounded it! It stopped working for a few days, but is now working again, just with alot of noise.
I have a regular scope, can someone point me to what i should be able to measure “place x and y” to find the faulty component?
EDIT: Forgot to say that my amplitude is very low… Is there any way to see if the U9 (74HC125) is dead?
