The National Instruments 785353-01 Vector Signal Transceiver, designated as PXIe-5840, represents a cutting-edge second-generation solution tailored for sophisticated wireless communication testing. This high-performance device integrates a vector signal generator, vector signal analyzer, and high-speed serial interface into a compact 2U PXI Express form factor, providing exceptional functionality within a streamlined design. Operating across a frequency range of 9 kHz to 6 GHz, the transceiver delivers an impressive instantaneous bandwidth of up to 1 GHz, making it suitable for a diverse array of wireless and cellular standards, including IEEE 802.11ax.

The 785353-01 showcases precise tuning capabilities with a resolution down to 888 nHz and programmable local oscillator (LO) step sizes in both fractional and integer modes. Its robust RF input stage can handle signals ranging from the noise floor to +30 dBm, ensuring high precision and fidelity through advanced spurious response handling and optimized third order intercept points. This versatility extends to the RF output, which maintains a power range up to +20 dBm, dependent on frequency, with low noise density and excellent intermodulation distortion performance, crucial for generating clean signals in various test conditions.

Powered by a Xilinx Virtex-7 FPGA, the device is equipped with up to 866,400 flip-flops and 52.9 Mbits of embedded block RAM, allowing for real-time signal processing that enhances test setup complexity while minimizing latency. Moreover, the transceiver supports high-speed data transfer across multiple DMA channels, enabling efficient management of substantial data streams. Designed to endure demanding environments, the 785353-01 operates reliably within an ambient temperature range of 0 °C to 45 °C and is also shock-resistant up to 30 g peak, functioning effectively at altitudes up to 2,000 meters. The module's physical dimensions are 4.1 cm × 12.9 cm × 21.1 cm (1.6 in. × 5.6 in. × 8.3 in.), and it weighs 794 g (28.0 oz). This product comes with a warranty period of 2 to 3 years, ensuring confidence in its durability and performance.
