The following scenarios will be tested:

\item Open termination
\item Short termination
\item Matched termination

\subsection{Setup}
All measurements will be taken using the setup in Figure \ref*{fig:setup}.

In initial tests, it was found that using a single BNC cable between the terminator and the function generator would produce a reflection, however it would overlap with the original signal, making it difficult to take any measurements. Therefore the setup was built using three cables instead of one in order to delay the reflection to a point where it can be measured. The cables were connected using BNC male to male connectors, making the total cable length about 3 meters.
