The simplest way to setup your environment consists of cloning the PItSTOP Project onto your Client:
\begin{minted}{bash}
\begin{mintylst}{bash}
$ git clone https://url.to.pitstop

then substituting the \verb|rsync| targeti:

\begin{enumerate}
\item divide our input voltage into a usable potential range
\item decouple the input from our signal potential
\item operate within the Chips possible Voltage range of 0-3.3V
\item operate within the Chips possible Voltage range of 0 -- 3.3V
\end{enumerate}
The already implemented Cicuit can be seen in figure \ref{mon48v}. It consists of a 1:240 Voltage Divider, a full differential operational amplifier taking in the ~200mV (nominal), and amplifying it by a factor of 8 ($r_\text{diffOpAmp}$). It is decoupling the input and output voltages, so our 48V and 3.3V circuit parts are electricly insulated. The remaining operational amplifier provides futher amplification by a factor of 1.1 ($r_\text{OpAmp}$)
