GETTING STARTED GUIDE
NI 5751/5751B
50 MS/s Digitizer Adapter Module
Note
Before you begin, complete the software and hardware installation
instructions in your FlexRIO FPGA getting started guide or controller for FlexRIO
getting started guide.
Caution
may impair the protection the NI 5751/5751B provides.
The NI 5751/5751B is a 50 MS/s, 14-bit high-speed digitizer adapter module designed to work
in conjunction with FlexRIO FPGA modules and controllers for FlexRIO. The NI 5751/5751B
features 16 analog input channels and 8 bidirectional digital I/O channels.
This document explains how to install and configure the NI 5751/5751B.
The NI 5751B variant is compatible with all FlexRIO FPGA modules and controllers for
FlexRIO. The NI 5751 variant is compatible with the NI PXI-795xR and NI PXIe-796xR
FPGA modules only.
Note
NI 5751R refers to the combination of your NI 5751/5751B adapter module
and either a FlexRIO FPGA module or a controller for FlexRIO. NI 5751/5751B
refers to your adapter module only.
