Hi! friends


I want to check the high-impedence state of the pin...

I have options 1.Multimeter 2.DSO

How can i found whether the pin is in High-impedence State or not
 

Re: High impedence state

You need a Logic probe with two ouputs one for low another for High.

If none of the ouputs were asserted when you probe the pin to be tested then that pin is in high impedance state.

I have made my self one probe with two comparators. Its easy, try it
