- | The S800 trigger provides a vetoed 10 MHz clock signal (derived from the 40 MHz FPGA clock) used for time stamping. An external clock can also be used, after selecting the appropriate check box in the [[Trigger# | + | The S800 ULM trigger |
- | The time stamping clock is available as an output that can be distributed to other time stamp modules, such as the one located in the S800 VME crate, or in other data acquisition systems coupled to the S800. | + | The time stamping clock is available as an output that can be distributed to other time stamp modules, such as the one located in the S800 VME crate (or in other data acquisition systems coupled to the S800).
