It would be fairly obvious to most of us that if we put an oscilloscope on a digital signal and found it not to be within the required voltages that we would suspect a problem.


Thanks dear Russell for your reply
But is it possible for us to use from oscope all times/all places,assume that You sell your system to a customer that he/she is far from you many miles,
when he/she call you about this error,"the system has internal error"
I never carry my oscope to his/her city
I only take some used ic in that system
also maybe i would say him/her plaese present your system here
Best
