Description
The National Instruments PXIe-7856 is a high-performance PXI Multifunction Reconfigurable I/O Module featuring eight analog inputs and outputs, as well as 48 digital input/output channels.
It has part numbers PXIe-7856R and 784145-01, and is capable of a sample rate of 1 MS/s, allowing for rapid data acquisition and processing.
Equipped with a powerful Kintex-7 160T FPGA, this module offers substantial computational capabilities right on the hardware itself.
The integration of two 68-pin VHDCI I/O connectors facilitates extensive connectivity options, while each channel’s dedicated Digital-to-Analog Converter (DAC) ensures precise control over signal outputs.
With 2 LVTTL, LVCMOS compatible digital I/O connectors, it accommodates a wide range of digital signals, and the logic level can be easily set via software, defaulting at 3.3V.
The module’s first digital I/O connector supports signals with a maximum frequency of up to 10 MHz across 16 channels, whereas the second connector accommodates higher-speed signals of up to 80 MHz on 32 channels.
