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.

LED
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.
