Time Tagger Q420 is a single width PXIe module. It provides four count inputs and a fifth input for offset time tagging. The clock is locked to the 100MHz differential PXIe clock. The counts can be gated via the PXI trigger lines. Counts are returned over the PCIe bus to the main system memory and are accessible via an API.
