The NI PXI-6581R is a 100 MHz digital instrument built on the NI FlexRIO platform. It features 54 single-ended digital channels. You can configure the instrument for 1.8, 2.5, 3.3, or 5 V (TTL) logic. You can also use an external source as a voltage reference by connecting the external source to the front panel connector.

The PXI-6581R consists of the NI 6581 adapter module and an NI PXI-795x field-programmable gate array (FPGA) module for NI FlexRIO. The NI FlexRIO FPGA module features a user-programmable FPGA chip for onboard processing and flexible I/O operation. Using NI LabVIEW graphical block diagrams and the LabVIEW FPGA Module, you can configure all the digital functionality. Your block diagram executes in hardware, giving you complete control over all digital I/O signals for applications such as:

-Custom protocol emulation and testing
-Serial triggering
-Custom onboard signal processing
-Hardware-implemented algorithms

You can use this instrument with the NI-RIO driver and LabVIEW FPGA for not only high-speed digital acquisition and generation but also hardware-implemented signal processing and control.

Required Software
This product requires the LabVIEW FPGA Module 8.5.1 and NI-RIO 2.4 or later driver software.

New Virtex-5 FPGA
The new Virtex-5 FPGA architecture is optimized to execute faster and more efficiently using single-cycle timed loops in LabVIEW FPGA. This means you can optimize more LabVIEW FPGA code to fit within Virtex-5 FPGAs and execute more operations per clock cycle.
