I/Q Acquisition Programming Flow
Use the programming flow shown in Figure 7 and Figure 8 to acquire I/Q data in single-shot or
continuous modes, respectively. Use the ni5660 Configure for IQ Settings VI and the ni5660 Read IQ
VI when Acquiring Single-Shot I/Q Data. Use the ni5660 Configure for IQ Settings VI, the ni5660
Initiate IQ VI, and the ni5660 Fetch IQ VI when Acquiring Continuous I/Q Data.

Example Applications for LabVIEW
Several example ni5660 VI applications are available for LabVIEW. These examples are intended to
serve as interactive tools, programming models, and building blocks in your applications.
All installed ni5660 example files are located in the location specified in the
NI RF Signal Analyzers
Readme
.
LabVIEW examples demonstrate integration of the NI RF vector signal analyzer with
NI RF signal generators and NI toolkit software, including the Modulation Toolkit. Refer to the
