The Reflection Coefficient
TDR measurements are described in terms of a
Reflection Coefficient, (rho). The coefficient r is
the ratio of the reflected pulse amplitude to the incident pulse amplitude:
注:在绘制场图前必须先选择一个面或者一个多点 线。

What is Time Domain Reflectometry?
Time Domain Reflectometry (TDR) measures the reflections that result from a signal travelling through a transmission environment of some kind – a circuit board trace, a cable, a connector and so on.
Perform operations using drawing geometry or new geometry created in Post3
Perform operations at single frequency (interpolating or discrete sweeps) or other frequencies (fast sweep)
