Time Domain Reflectometry<br />
� Positive-going spikes indicate inductive changes to the impedance<br />
� Negative-going spikes indicate capacitive changes to the impedance<br />
� For the trace looking from the microstrip, we first see the inductance of the trace, then the capacitance of the via<br />
transition<br />
�� For better time (spatial) resolution resolution, we would need a smaller sampling time time, and thus a higher stop frequency <strong>for</strong> our<br />
sweep
