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}). + +\begin{figure}[htp] + \centering + \includegraphics[width=0.8\textwidth]{figures/tdcTrigWinWF.png} + \caption{An illustration of trigger window relative to the reference time.} + \label{fig:tdcTrigWin} +\end{figure} \ No newline at end of file diff --git a/trb3/main.tex b/trb3/main.tex index c8a346e..eaf0520 100755 --- a/trb3/main.tex +++ b/trb3/main.tex @@ -134,10 +134,10 @@ \input{DesignComponents} \clearpage \section{TDC} - \subsection{Features} - \input{TdcFeatures} \subsection{Building Blocks} \input{TdcBuildingBlocks} + \subsection{Features} + \input{TdcFeatures} \subsection{Data Format} \input{TdcDataFormat} \subsection{Slow Control Registers} -- 2.43.0
