This asynchronous trigger from the detector is processed and synchronised at the Central Trigger System (CTS) and a data readout trigger is sent to the End Points, e.g. TDCs. The arrival of this readout trigger is measured and stored at the Reference Channels (Channel 0) of the TDCs. However, as this data readout trigger is synchronised to the system clock at the CTS, it doesn't carry real time information of the trigger from the detector. The time information at the Reference Channel should be used to synchronise all of the TDCs in the system. In order to calculate the relative hit times to the asynchronous trigger from the detector, the asynchronous trigger must be physically applied to a channel input of a TDC and the time information must be gathered. In future designs the measurement of the asynchronous trigger signal will be done in the CTS by an embedded TDC but confirm the design version you are using by contacting one of the developers! \ No newline at end of file -- 2.43.0
