National Instruments 782376-01 RF Vector Signal Transceiver

The National Instruments 782376-01 (Model Name: PXIe‑5644R) is a versatile RF Vector Signal Transceiver (VST) that integrates both vector signal generation and analysis capabilities. The model has a frequency range spanning from 65 MHz to 6 GHz. It is equipped to handle a wide variety of wireless communication standards and protocols. This VST offers an 80 MHz instantaneous bandwidth which is crucial for capturing and analyzing wideband signals in real time.

The National Instruments 782376-01 can deliver CW signals up to +15 dBm below 4 GHz and up to +12 dBm above 4 GHz along with modulation capabilities allowing for comprehensive signal testing and generation. The output power level accuracy is also tightly controlled along with typical deviations within ± 0.26 dB ensuring that the transmitted signals maintain their integrity. The device's digital to analog and analog to digital converters both operate at 120 MS/s with 16 bit resolution that provides high fidelity signal conversion. The 782376-01 features a highly accurate frequency tuning resolution of less than 1 Hz that allows for precise control over the generated and analyzed signals. The device supports both fractional and integer frequency modes with programmable step sizes as fine as 200 kHz. The instrument's frequency settling time is minimized across low, medium and high loop bandwidth settings that ensures that frequency changes are stable and quickly achieved.

This Vector Signal Transceiver has low single sideband phase noise across its operating range ensuring that signals are clean and free from unwanted spectral components. The RF input accommodates a wide amplitude range from the noise floor up to +30 dBm with an amplitude settling time of 125 μs for fast and precise level adjustments. The absolute amplitude accuracy is finely tuned along with typical accuracies within ± 0.34 dB ensuring that the measurements are reliable and consistent across a broad frequency spectrum. The onboard Xilinx Virtex-6 FPGA enhances the 782376-01 module's processing capabilities and enables real-time signal processing and customization through user programmable algorithms. The FPGA facilitates complex signal processing tasks with 124,800 logic cells and a data transfer rate of up to 2.1 GB/s per bank. The device's compact form factor is designed for PXI Express systems.
