The National Instruments 782952-01 RF Vector Signal Transceiver, also known as the PXIe‑5646R, is a powerful multifunction device that combines a vector signal generator and vector signal analyzer, equipped with FPGA-based real-time signal processing capabilities. This model operates within a frequency range of 65 MHz to 6 GHz, delivering RF instrument-grade performance with the flexibility of a software-defined radio architecture. The transceiver produces output power from the noise floor to +15 dBm, with a fine resolution of 0.1 dB, and offers a high level of output frequency response precision, showing typical deviations of ±0.5 dB. This advanced performance makes it ideal for applications that demand highly accurate signal synthesis and modulation.

Weighing 1,360 g and measuring 6.1 cm × 12.9 cm × 21.1 cm, the 782952-01 supports various wireless and cellular standards, including 802.11ac and LTE‑A, with instantaneous bandwidth options from 20 MHz to 200 MHz based on the center frequency. Its frequency settling time is adaptable, with maximum times as low as 0.38 milliseconds achievable with high loop bandwidth settings. The internal frequency reference boasts an initial accuracy of ±200 ppb, ensuring reliable frequency stability over temperature and aging.

For the RF input section, the transceiver provides an amplitude range from the average noise level to +30 dBm, with resolution in nominal 1 dB steps over a range of ≥60 dB and an input frequency response calibrated to minimize variations as low as ±0.5 dB across the majority of the operational spectrum. The average noise density can reach as low as -161 dBm/Hz, facilitating the detection of extremely low-level signals. The onboard Xilinx Virtex-6 FPGA, featuring 150,720 LUTs and 301,440 flip-flops, equips the 782952-01 with robust signal processing capabilities, enabling high data processing tasks at a transfer rate of up to 2.1 GB/s per bank. With comprehensive I/O options including SMA connectors for RF and local oscillator signals, the 782952-01 RF Vector Signal Transceiver is a versatile solution for modern RF applications.
