National Instruments 782952-01 RF Vector Signal Transceiver

The National Instruments 782952-01 (PXIe‑5646R) RF Vector Signal Transceiver (VST) is an advanced, multifunctional device that integrates a vector signal generator and vector signal analyzer with FPGA based real time signal processing and control capabilities. This design offers the flexibility of a software defined radio architecture while maintaining RF instrument grade performance. The model operates across a frequency range of 65 MHz to 6 GHz. The Vector Signal Transceiver delivers power across a range from the noise floor to +15 dBm that depends on the output frequency along with fine resolution down to 0.1 dB. The output frequency response is similarly precise along with typical deviations of ±0.5 dB.

This precise control and stability make it suitable for applications requiring highly accurate signal synthesis and modulation. The model weighs 1,360 g (48.0 oz) and has physical dimensions of 6.1 cm × 12.9 cm × 21.1 cm (2.4 in. × 5.6 in. × 8.3 in.). The 782952-01 model supports a variety of wireless and cellular standards, including 802.11ac and LTE‑A with instantaneous bandwidth options ranging from 20 MHz to 200 MHz depending on the center frequency. The vector signal transceiver's frequency settling time varies with loop bandwidth settings and offers maximum settling times as low as 0.38 milliseconds for high loop bandwidth scenarios. The internal frequency reference features an initial adjustment accuracy of ±200 ppb that ensures precise frequency control with excellent stability over temperature and aging.

The RF input section of the 782952-01 provides an amplitude range from the average noise level up to +30 dBm along with a resolution of 1 dB nominal steps over a range of ≥60 dB. The input frequency response is well calibrated with variations as low as ±0.5 dB across most of its operating range. The average noise density is specified to reach as low as -161 dBm/Hz that enables the detection and analysis of very low-level signals. The 782952-01 model’s onboard Xilinx Virtex-6 FPGA features 150,720 LUTs and 301,440 flip-flops and provides robust signal processing capabilities. This transceiver supports intensive data processing tasks with a high data transfer rate of up to 2.1 GB/s per bank. The module's extensive I/O options include SMA connectors for RF and LO signals.
