Description The PhotoniQ Model IQSP518 is an economical multi-channel data acquisition system designed to offer scientists, engineers, and developers an off-the-shelf solution for data collection from multiple charge-based sensors. Implemented as a stand-alone laboratory instrument with a PC interface, the PhotoniQ is used for charge integration and data acquisition from individual photomultiplier tubes, avalanche photodiodes, and silicon photomultipliers (SiPM). Available in a standard configuration of two input channels, the IQSP518 can be expanded in the factory or field to up to eight parallel channels. Flexible, intelligent triggering and acquisition modes allow the unit to reliably capture event or image data using sophisticated data acquisition techniques. The IQSP518 is fully configurable over its USB 2.0 port using an included graphical user interface. Continuous high speed data transfers to the PC are handled through this interface, or for custom applications through the provided Windows DLL set.
