More measurement on Potato TDR circuit

This is a continuation to my recent potato chip to TDR circuit posting at
http://www.epanorama.net/newepa/2018/10/16/potato-chip-to-tdr-circuit/

Here are some measurement results made with high speed oscilloscope (at shortest pulse setting and 50 ohms impedance). Blue measurement with circuit directly connected to scope and yellow wirh 10x scope probe.
