Thanks to all who replied. Here is some more information. Here is the cable: goo.gl/Sbrsgi Thank you for pointing me to those references. I will take a look at them. The line is terminated with a 78 ohm resistor when I measure at the stubs along the line. When I measure at the end of...

Thank you for your reply. I should have mentioned that the line is terminated on both ends with its characteristic impedance of 78 ##\Omega##. I suppose that there will still be some slight reflections though, since it's unlikely to be perfectly matched. Would it then be a good idea to place...

I am measuring a communications bus with an oscilloscope at various points along the line. I understand that there will be reflections at each stub as well as at the ends of the bus if the impedance doesn't match. I also understand that these reflected signals will add/subtract with the...
