NI 5761R User Guide and Specifications

Clocking

The NI 5761 clocks control the sample rate and other timing functions on the device. Table 3 contains 
information about the possible NI 5761 clock resources.

Using Your NI 5761R with a LabVIEW FPGA Example VI

The NI FlexRIO Adapter Module Support software includes a variety of example projects to help get 
you started creating your LabVIEW FPGA program. This section explains how to use an existing 
LabVIEW FPGA example project to generate and acquire samples with the NI 5761R. This example 
requires at least one SMA cable for connecting signals to your NI 5761R.

Note

Examples available for your device are dependent on the device-specific minimum software 

requirements. For more information about software requirements for your device, visit 

ni.com/

info

 and enter 

rdsoftwareversion

 as the Info Code to determine which minimum software 

versions you need for your device.

Each NI 5761R example project includes the following components:

•

A LabVIEW FPGA VI that can be compiled and run embedded in FPGA hardware

•

A VI that runs in LabVIEW for Windows and interacts with the LabVIEW FPGA VI

Note

In NI application software, NI FlexRIO adapter modules are referred to as 

IO Modules

.

Complete the following steps to run an example that acquires a waveform on CH 0 of the NI 5761.

1.

Connect one end of an SMA cable to CH 0 on the front panel of the NI 5761 and the other end of 
the cable to your device under test (DUT).

2.

Launch LabVIEW.

3.

In the 

Getting Started

 window, click 

Find Examples

 to display the NI Example Finder.

4.

In the 

NI Example Finder

 window, select 

Hardware Input and Output»FlexRIO»IO Modules»

NI 5761

.

5.

Select 

NI 5761 - Getting Started.lvproj

.

6.

In the 

Project Explorer

 window, open 

NI 5761 - Getting Started (Host).vi

 under 

My Computer

. 

The host VI opens. This VI uses the NI 7952R as the FPGA target by default. If you are using an 
NI FlexRIO FPGA module other than the NI 7952R, complete the following steps to change to an 
FPGA VI that supports your target.

a.

Select 

Window»Show Block Diagram 

to open the VI block diagram.

b.

On the block diagram, right-click the Open FPGA VI Reference (PXI-7952R) function and 
select 

Configure Open FPGA VI Reference

.
