The National Instruments PXI-7833 is a Multifunction Reconfigurable I/O Device designed for high-performance applications within the PXI platform. This R Series device features a Virtex-II V3000 FPGA, enabling users to tailor its timing and functionality to specific requirements. With eight 16-bit analog input channels capable of sampling at 200 kS/s and eight 16-bit analog output channels operating at 1 MS/s, the PXI-7833 supports versatile data acquisition needs. The device is compatible with multiple input modes, including Differential (DIFF), Non-Referenced Single-Ended (NRSE), and Referenced Single-Ended (RSE), which can be selected via software, allowing all channels to share the same configuration.

In addition to its analog capabilities, the PXI-7833 provides 96 digital I/O channels that can be independently configured for input or output operations. It integrates three 68-pin VHDCI connectors for connectivity, making it easy to interface with various external systems. The device also includes calibration digital-to-analog converters (DACs) to minimize measurement errors, supporting self-calibration and external calibration for enhanced accuracy. Data handling and real-time processing capabilities are further facilitated by the required LabVIEW RT software. The PXI-7833's onboard flash memory allows for storage of startup virtual instruments (VIs), with the FPGA capable of automatic loading upon power-up. It incorporates a PXI local bus for communication with other PXI modules, ensuring seamless integration within complex systems. The dimensions of the PXI-7833 are 6.3 inches by 3.9 inches, with a weight of 0.33 pounds, making it a compact solution suitable for various applications. Although declared obsolete, the PXI-7833 remains available for purchase and repairs through Apex Waves.
