The National Instruments 782376-01, known as the PXIe‑5644R RF Vector Signal Transceiver (VST), is a highly versatile instrument designed for both vector signal generation and analysis. It operates within a frequency range of 65 MHz to 6 GHz, making it suitable for a diverse array of wireless communication standards and protocols. With an instantaneous bandwidth of 80 MHz, the device excels at capturing and analyzing wideband signals in real-time, offering continuous wave (CW) signal outputs up to +15 dBm below 4 GHz and +12 dBm above 4 GHz. The signal integrity is ensured by tightly controlled output power level accuracy with typical deviations not exceeding ± 0.26 dB.

The 782376-01 features high-fidelity digital-to-analog and analog-to-digital converters, both operating at 120 MS/s with 16-bit resolution, along with a frequency tuning resolution of less than 1 Hz that allows for precise control over both generated and analyzed signals. It supports both fractional and integer frequency modes, programmable with step sizes as fine as 200 kHz, and minimizes frequency settling time across various loop bandwidth settings. The transceiver maintains low single sideband phase noise across its operating range, ensuring clean signals without unwanted spectral components.

The RF input can accommodate signals ranging from the noise floor to +30 dBm, with an amplitude settling time of 125 μs for rapid and accurate level adjustments. The absolute amplitude accuracy is finely calibrated with typical deviations within ± 0.34 dB, ensuring reliable measurements across wide frequency ranges. Enhanced by an onboard Xilinx Virtex-6 FPGA with 124,800 logic cells, the 782376-01 allows for real-time signal processing and customization via user-programmable algorithms, supporting high data transfer rates of up to 2.1 GB/s per bank through its dual 256 MB DRAM banks. Engineered for efficient integration into PXI Express systems, the compact dimensions of 6.1 cm × 12.9 cm × 21.1 cm and a weight of 1,360 g (48.0 oz) make this module ideal for a variety of industrial and research applications. The 782376-01 comes with a warranty of 2 to 3 years, ensuring long-term reliability and support.
