Appendix B: Building a Basic NI-RFSG Application
NI-RFSG includes several example applications for both LabVIEW and 
LabWindows/CVI. These examples are intended to serve as interactive 
tools, programming models, and as building blocks in your own 
applications. 
LabVIEW and LabWindows/CVI users can access all installed NI-RFSG 
examples at Start»All Programs»National Instruments»
NI-RFSG»Examples
. LabVIEW users can access NI-RFSG examples by 
running LabVIEW and selecting Help»Find Examples to launch the 
LabVIEW Example Finder. 
You can complete the following steps in LabVIEW to build a basic 
NI-RFSG application for generating continuous sine wave signals:
1.
Select Start»All Programs»National Instruments»<LabVIEW>» 
LabVIEW 
to launch LabVIEW. The LabVIEW screen appears.
2.
Click New, choose Blank VI, and click OK to create a blank VI.
3.
Display the block diagram by clicking it or by selecting Window»
Show Block Diagram
.
4.
Activate the LabVIEW context help by pressing <Ctrl-H>. 
5.
Click the LabVIEW block diagram to launch the Functions palette.

Indications
ACCESS
Indicates the basic hardware status of the NI 5650/5651/5652 module.
OFF—The module is not yet functional or has detected a problem with a PXI 
power rail.
AMBER—The module is being accessed.
GREEN—The module is ready to be programmed.
ACTIVE
Indicates the status of the NI 5650/5651/5652.
OFF—The module is in an uninitialized state; there is no error.
AMBER—The module PLLs are attempting to lock.
GREEN—The module is generating a signal; applicable PLLs are locked.
RED—The module has detected an error state; this may indicate lock failure in 
an applicable PLL, a self-test or calibration failure, or a thermal shutdown 
condition.
