National Instruments has announced 10 blocks of application IP as part of its offering to allow engineers to build custom RF instruments in LabVIEW.
This IP integrates with PXI FPGA targets such as the PXIe-5644R vector signal transceiver (VST) and extends their default capabilities by adding new features or enhancing performance in specific applications.
Examples of the IP include: hardware power servoing for RF amplifier test, RF channel impairments including fading, noise, multipath and Doppler effects, digital device under test control and contiguous I/Q waveform streaming to and from disk.
