National Instruments PXIe‑5645 PXI Vector Signal Transceiver

The PXIe-5645, previously known as the PXIe-5645R, (Part Number: 782377-01) Vector Signal Transceiver by National Instruments has the following features:

·         High-Speed Digital I/O Up to 250 Mbit/s

·         200 MHz maximum instantaneous/complex I/Q bandwidth

·         NI-TClk for easy synchronization for MIMO configurations

·         LabVIEW-programmable FPGA

·         24 Channels

The NI PXIe‑5645 Vector Signal Transceiver addresses the requirement of engineers for a higher bandwidth by offering FPGA-based signal processing for applications, such as radar target simulation, multi-carrier aggregation, DPD algorithm implementation, 5G prototyping, and real-time spectrum analysis. This model provides instantaneous and complex I/Q bandwidth which functions for improved measurement precision.

The PXIe 5645 supports an RF frequency range from 65 MHz to 6 GHz. It is a high-performance Vector Signal Transceiver that is designed for advanced application testing. The NI PXIe‑5645 is a versatile form factor that can either be used as a vector signal generator or vector signal analyzer. This model additionally features FPGA-based real-time signal processing and control. The PXIe‑5645 has a differential or single-ended baseband I/Q interface. The NI PXIe‑5645 provides phase noise (10 kHz offset) up to -112 dBc/Hz, VSG amplitude accuracy up to ±0.6 dB, and has a tuning time of 380 µs.

Its small form factor, a production test box configuration, and fast measurement speed make the PXIe-5645 an R&D-grade box instrument. This Vector Signal Transceiver is software-designed as it is built on a LabVIEW FPGA. This model features several starting points for applications, including application IP, reference designs, examples, and LabVIEW sample projects, while also giving users the ability to completely customize the onboard processing.
