PXI I/O MODULES Four R Series I/O modules for the PXI platform are equipped with Xilinx Virtex-5 field programmable gate arrays (FPGAs). The PXI-7841R, PXI-7842R, PXI- 7851R and PXI-7852R modules have eight analog inputs, eight analog outputs and 96 digital I/O lines, as well as analog input rates that are more than 3.5 times faster than previously released R series devices. These modules provide engineers with commercial off-the-shelf hardware that can be graphically programmed with the LabView FPGA module to perform custom onboard processing for inline data analysis and deterministic I/O control for applications that require specialized timing and triggering.
