NI PXI series PXI-7854 Module for Test Measurement & Automation Systems

The NI PXI-7854 is a high - performance, multifunction reconfigurable I/O module designed for PXI Express systems. Here is a detailed introduction:

Hardware Architecture

FPGA - based Design: It is equipped with a Virtex-5 LX110 FPGA, which enables users to program and customize the module's functionality according to specific application requirements. This allows for high - performance onboard processing and direct control over I/O signals, ensuring flexibility in system timing and synchronization.

Analog I/O: The module has 8 analog input channels with a 16 - bit resolution and a maximum sampling rate of 750 kS/s per channel. The input voltage range is - 10 V to 10 V. There are also 8 analog output channels with a 16 - bit resolution and a maximum output frequency of 10 MHz. Each channel is equipped with a dedicated analog - to - digital converter (ADC), enabling independent timing and triggering, and providing special functions such as multi - rate sampling and single - channel triggering.

Digital I/O: It provides 96 bidirectional digital I/O lines, which support TTL logic levels. These lines can be configured as inputs, outputs, counter/timers, PWM, flexible encoder inputs, or specialized communication protocols according to user needs.

Software Support: The NI PXI - 7854 is supported by software such as NI LabVIEW, NI C/C++, and NI Python. Users can use the LabVIEW FPGA module to customize the module and develop applications that require precise timing and control through LabVIEW graphical block diagrams, such as hardware - in - the - loop (HIL) testing, custom protocol communication, sensor simulation, and high - speed control.

Applications: This module is suitable for a variety of applications, including electronic testing, automotive testing, aerospace and defense testing, industrial automation, and research and development. Its combination of analog and digital I/O capabilities, along with reconfigurability and synchronization features, makes it a versatile module for a wide range of test and measurement scenarios.
