\begin{itemize}  \item \textbf{SKA1-SYS\_REQ-XXXX:} \textit{\bf SKA1\_Mid Pulsar Timing incoherent dedispersion DM limits.} The SKA1\_Mid when in pulsar timing mode shall time pulsars using incoherent dedispersion up to a dispersion measure defined by ${\rm DM} = t_{\rm res}(4.15\times10^3 (\nu^{-2} - (\nu+\delta\nu)^{-2}) )^{-1}$ pc cm$^{-3}$. Where $\nu$ is the bottom frequency of the current observing band, $\delta\nu=20\pm50\%$ Hz and $t_{\rm res}$ is a user-defined effective time resolution.  \item \textbf{SKA1-SYS\_REQ-XXXX:} \textit{\bf SKA1\_Low Pulsar Timing incoherent dedispersion DM limits.} The SKA1\_Low when in pulsar timing mode shall time pulsars using incoherent dedispersion up to a dispersion measure defined by ${\rm DM} = t_{\rm res}(4.15\times10^3 (\nu^{-2} - (\nu+\delta\nu)^{-2}) )^{-1}$ pc cm$^{-3}$. Where $\nu$ is the bottom frequency of the current observing band, $0.5 < \delta\nu < 2.0$ Hz,  $\delta\nu=1\pm50\%$ Hz and $t_{\rm res}$ is a user-defined effective time resolution. \end{itemize}
