PCIe-9146DAQ board with 16-bit FPGA and simultaneous sampling
- Manufacturer
PCIe-9146 is a data acquisition board with a built-in FPGA for the PCI Express bus, meant for test applications where sample processing has to happen on the board, before the data reaches the PC.
Simultaneous sampling keeps the analog channels aligned in time, a condition that is needed when correlated signals are compared. Input ranges are selectable in software, from the narrowest ±0.3125 V up to ±10 V, with DC coupling.
