The C400 counts fast pulses generated by photomultipliers, avalanche photodiodes, and similar devices. It has four parallel channels that are configurable independent of each other. It provides high voltage bias for sensors and low voltage power for preamplifiers. Several units can measure in sync using a common trigger or encoder pulses.
Measurement data is transmitted through state-of-the-art fiber-optic cables. The benefits are numerous compared to other forms of data transmission.
