The Expression Scanner is a software add-on for LabVIEW that you can use for expression scanning in streaming data with the LabVIEW Real-Time Moduleand LabVIEW FPGA Module. This add-on is compatible with FPGA targets such as CompactRIO hardware, Industrial Controllers, USRP Software Defined Radio Devices, spectrum and signal analyzers, and more. The Expression Scanner can be adapted to be used in single-cycle Timed Loops, and it can be used in complex cascaded scan applications.
