Re: Non-terminal snubbers

Check the current flow near the end of each buss. I found a spike near the end of a roughly 45’ buss using my RRamp Meter. I installed an NCE snubber and it disappeared.

Hi Gang:

How do you know if you need snubbers? What do you see? Is there a test?

Michael, no it’s not needed.
The purpose of the snubber is to reduce the reflected signal at the end of an unterminated buss; not needed in the center of a buss.

Would it help to put a snubber midway on the 38 foot bus?
