\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 ${\rm DM} = t_{\rm res}(4.15\times10^3 (\nu^{-2} - (\nu+1/t_{\rm res})^{-2}) )^{-1}$ pc cm$^{-3}$, with a maximum of 100,000 pc cm$^{-3}$, where the frequency ($\nu$) is defined as the top of the current observing band and the time resolution ($t_{\rm res}$) is defined by SKA1-SYS\_REQ-2961.   \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 ${\rm DM} = t_{\rm res}(4.15\times10^3 (\nu^{-2} - (\nu+1/t_{\rm res})^{-2}) )^{-1}$ pc cm$^{-3}$, with a maximum of 10,000 100,000  pc cm$^{-3}$, where the frequency ($\nu$) is defined as the bottom of the current observing band and the time resolution ($t_{\rm res}$) is defined by SKA1-SYS\_REQ-2962. \end{itemize}
