National Instruments PXIe-5644R/5645R vector signal transceivers

The National Instruments PXIe-5644R/5645R vector signal transceivers (VST) are part of a class of instrumentation that combines a vector signal generator and vector signal analyser with FPGA-based real-time signal processing and control. Because of this software-designed approach, a VST features the flexibility of a software-defined radio architecture with RF instrument-class performance.

The 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. The single instrument approach gives faster test times using the latest PC and FPGA technologies.

Product features include: 65 MHz to 6 GHz frequency range, 80 MHz instantaneous bandwidth and 24 channels of high-speed digital I/Q; baseband I/Q interface with 16-bit data sampled at 120 MS/s with up to 80 MHz of complex bandwidth, configurable as differential or single-ended; open, programmable FPGA that engineers can customise to add user-defined functionality.

Users can download prebuilt and modifiable IP for the most common applications.
