\title[Grand DU]{Channel delays in the Grand Digitizer}
\date{May 31, 2022}
\author{E.T. de Boone}

\frame{\titlepage}
\begin{frame}{Wireless time distribution}
\begin{block}{Current Timing Methods}
\begin{itemize}
\item GNSS (online)
\item Beacon (online/offline)
\end{itemize}
\end{block}
\vspace{2em}
\begin{itemize}
\item GPS Accuracy $\leq 30 \mathrm{ns}$ for $95$\% time (often better)
\item Total time accuracy in the order of 5 -- 10~ns
\end{itemize}
\vspace{2em}
\begin{alertblock}{Grand Digitizer}
\begin{itemize}
\item Both GNSS and Beacon,
\item Maybe test GNSS with Beacon?
\end{itemize}

\section{Channel Delays in the GRAND DU}
\begin{frame}{Grand DU before ADC}
\begin{block}{Grand DU before ADC}
\begin{itemize}
\item Four channel ADC
\item Per-channel Filterchain (might introduce delays)
\end{itemize}

\begin{frame}{Channel Delays Setup}
\begin{block}{Channel Delay Setup}
Single input into two channels\\
$\mapsto$ delays due to cabling and filterchain\\
\\
Use correlation or phase differences to determine delay

\begin{block}{What signal to put in?}
\begin{itemize}
\item Sine, $\mapsto$ single frequency response of chain
\item Pulse, $\mapsto$ multiple frequencies to compare
\end{block}

# Short Presentation on current status
Mostly to show what I've been doing uptil now.
Add short description of experimental setup?
### Outline
* Timing Mechanisms (GNSS, Beacon)
* White Rabbit as reference timing mechanism
* White Rabbit
* PTP
* Fourier and Phase information
* precise measurement $N_{sample} = N_{required}$
* imprecise measurement $N_{sample} != N_{required}$
