Fast trigger and sync

The DLnsec includes an internal trigger source that can be used if pulses don’t have to be shorter than 50 ns and rep-rates not higher than 62 kHz. If you want it fast, the DLnsec™ can be triggered by an external TTL source. Independent of the source used to trigger the light pulses, the DLnsec™ comes with a synchronous LVTTL output. This signal is triggered by the internal current pulse driver circuit and has only a very short delay of a few nanoseconds with respect to the emitted light pulse with jitter on the order of only a few tens of picoseconds. This allows triggering  measurements very precisely on the emitted light pulse.
