Reflection from a short.
Shorts and other decreases in impedance cause negative
spikes on the trace.
Reflection from a section of cable with the wrong impedance
(followed by the end of the cable).
The small positive spike at the start of the section indicates
higher impedance than the rest of the cable. The negative
spike is the end of the section, where the impedance drops to
the correct value.
