Second Vector Signal Transceiver From NI Extends Innovative Software-Designed Instrumentation Platform


NI offers an I/Q interface on new vector signal transceiver (VST) instruments, which combine a vector signal generator and a vector signal analyzer with a user-programmable FPGA for real-time signal processing and control.
Engineers can use NI LabVIEW system design software to transform the VST into a new instrument or enhance its existing functionality.
The new VST module adds baseband I/Q capabilities to increase test coverage for RF transceiver test.

AUSTIN, Texas National Instruments today announced its second vector signal transceiver, the NI PXIe-5645R, which is built on a software-designed architecture that engineers can modify with LabVIEW to meet their specific needs. The new vector signal transceiver adds a high-performance, differential or single-ended I/Q interface to test both the RF and baseband signals of a device with a single instrument for faster test times using the latest PC and FPGA technologies.

The software-designed architecture of the new NI PXIe-5645R vector signal transceiver provides users with unprecedented flexibility for applications such as RF transceiver baseband test, said Jin Bains, NI vice president of RF R&D.
