Laser setup connections

In order to take laser acquisitions the motherboard has a trigger output which uses the LEMO connector next to the USB connector (item 7 of Figure 2) for exciting a pulse generator which will drive the laser. The name of this output (TRIG OUT) is printed on the motherboard next to the corresponding connector.

The input of the pulse generator must have a 50 Ω termination and a coaxial cable of 50 Ω must be used for this connection. The levels of this motherboard output are 3.3 V LVTTL/LVCMOS compatible.
