\subsection{Measurements to be taken}
The following scenarios will be tested:
\begin{itemize}
\item Open termination
\item Short termination
\item Matched termination
\end{itemize}
For each scenario, the full dataset of the oscilloscope will be saved to CSV and analysed at a later moment using Python.

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.
