Yes, a MOHR TDR like the one shown in the video can measure accurately down to less than a picosecond equivalent distance. This translates to much less than a millimeter.

I remember a tek 1502 tdr back in the day. It was a nice piece of equipment to work with. Made by Tektronix, battery powered and good for field work.

Great simple video to understand basics of TDR. But, please keep ISO units to be more universal...

Thank you for the intuitive video. I have a question. What if there are multiple resistors connected to the cable at different locations?
@TheOriginalSycHolic5 жыл бұрын
they all would cause some kind of reflection, any break in the transmission line will cause this even proper termination points. this is why you use a TDR to make sure these losses arent above specs. Cable, fiber dont matter any kind of change in the transmission line will show a reflection this is how you test lines because you know it is there for a certain value. if its not then you got a problem. even a fiber weld shows up on a TDR. modern handhelds you dont even need a scope on them. they got TDR's now that are even network analyzers for QAM* data channels cable all in one...

Does it reflect back and forth multiple times making it something like a runtime oscillation?

What is the best way: To send one short pulse (about 100ns) or send a step? I assume the short pulse would get more attenuated when travelling through the cable? And the step would travel longer as it is DC after the step rising edge.

Hello sir. Do you suppose a TDR could be used to measure lengths in the order of a few inches? I have a 3-ft multiconductor coiled cable that I need to find the break in the wire for, and it would be helpful if I didnt have to split up the insulation badly to find the break. Thanks.
