John, thanks for your original suggestion and the followup. I have found it very useful.

While experimenting with it, I noted the extremely limited range of the original setup and found a method that allows viewing of the entire length of the line.
I described it in another thread at /g/nanovna-users/message/17561

Combining the two methods would allow the user to identify the general location of the defect and then zoom in on it using your updated method.

I would like to understand the reasons for each setting in your original post and a bit more detail of the use of the Electrical Delay feature, though. Would you mind giving a more detailed explanation?

Thanks,
Neil W0NRP.
