NI 5761R User Guide and Specifications

The NI 5761 is a 250 MS/s analog input adapter module designed to work in conjunction with your 
NI FlexRIO

 FPGA module. This document contains signal information and specifications for the 

NI 5761R, which is comprised of an NI FlexRIO FPGA module and the NI 5761. This document also 
contains tutorial sections that demonstrate how to acquire data using a LabVIEW FPGA example VI 
and how to create and run your own LabVIEW project with the NI 5761R.
