When connecting this side-on photon counting head H6240 series with a commercial available counter of TTL input, use a
50 ohm termination resistor or a 50 ohm feed-through termination (ex. TEKTRONIX 011-0049-01 etc.).
Please refer the notebook of the technical information about photon counting for more information.
