+\subsubsection{Trigger Window}
+\label{sec:tdcTrigWin}
+
+In order to reduce the data load on the DAQ a feature called trigger window is implemented. With this feature the user can define the interested time interval and filter the hits occurred in this time interval. An illustration of the trigger window feature is shown in Figure \ref{fig:tdcTrigWin}. The trigger window is relative to the rising edge of the reference time at the \textit{TRIGGER\_INP1} with the granularity of 5~ns. The \textit{Pre-Trigger Window} and \textit{Post-Trigger Window} widths can be set via slow control (Table \ref{tab:tdcControlReg}).
