National Instruments PCI-7833

The National Instruments PCI-7833 is a multifunction reconfigurable I/O module that integrates a client-programmable FPGA, specifically utilizing a Virtex-II V3000 architecture. This module offers robust analog and digital capabilities, featuring eight 16-bit analog inputs capable of sampling at 200 kS/s and eight 16-bit analog outputs with a rate of 1 MS/s. The PCI-7833 supports diverse input configurations, including Differential (DIFF), Single-Ended (RSE), and Non-Referenced Single-Ended (NRSE) modes, allowing for flexibility in interfacing with instrumentation amplifiers. In DIFF mode, each channel leverages two analog input lines for enhanced signal integrity, while in RSE mode, each channel uses a single positive input line referenced to ground, facilitating connections to floating sources through appropriate resistor biases. The module boasts 96 digital I/O channels, along with 28,672 flip-flops and 96 multipliers, delivering sufficient processing power for demanding applications. The PCI-7833 includes three 68-pin female high-density VHDCI connectors for I/O connections, and operates within a timebase range of 40 to 200 MHz. With power requirements of +3.3 VDC and +5 VDC, drawing 727 mA and 364 mA respectively, this unit measures 6.7 inches by 4.3 inches and weighs 0.25 lbs. It is supported by the NI-RIO driver and comes with a two to three-year warranty. Comprehensive user and maintenance manuals are available for download, with pricing information obtainable through a sales representative.
