TimeTagger dead time

What has to be considered with regard to the dead time respectively the input frequency for the TimeTaggers?

cronologic answer:

The term dead time refers to the time lag or time offset that can occur when measuring with a TDC. The dead time specified in the technical data of TDCs and the input frequency refer to the same parameter and are directly dependent on each other. An input frequency of 200 MHz, for example, corresponds to a double pulse resolution of 1/5 ns.

The extent to which this value is relevant for your measurement depends on the sensors used. Only in case the dead time of your sensors is extremely small and a high resolution is required, this value will be relevant for you.

The TimeTagger measures start and stop with the same resolution and bandwidth. Thus, starts at the distance of the double pulse resolution are also handled correctly - the dead time thus corresponds to the double pulse resolution in practice.
