NI PXI series PXI-7853R Module for Test Measurement & Automation Systems

NI PXI-7853R: I/O module with 16-bit analog input and output channels, 8 each, and nearly 100 bidirectional digital I/O lines, which can be flexibly configured and is often used for data transmission and monitoring of radar systems.

The NI PXI-7853R is a multifunction reconfigurable I/O module in the PXI series by National Instruments. It comes with the following features:

Versatile I/O Capabilities: It has 16-bit analog input and output channels, 8 each, and nearly 100 bidirectional digital I/O lines. These lines can be individually configured for input or output, supporting various measurement, control, and data acquisition applications.

High - Performance Acquisition: The module offers high - speed acquisition with a maximum sample rate of 750 ks/s, high resolution, and fast data transmission. This is crucial for accurately capturing and analyzing high - precision signals.

Reconfigurability: It adopts FPGA (Field - Programmable Gate Array) technology, enabling real - time reconfiguration. Users can customize the module's functions through programming to meet specific application requirements.

Multiple Interfaces: It is equipped with various interfaces and communication protocols like Ethernet, USB, and RS - 232, facilitating data exchange and communication with other devices and systems.

Software Support: The PXI - 7853R works seamlessly with NI's software platforms such as LabVIEW and NI - DAQmx. These software provide rich functionality and tools for easy configuration, control, and data analysis, simplifying the development and integration process.

Wide Application: It has been used in applications such as radar systems and bearing performance testing, demonstrating its reliability and stability in different industrial scenarios. For example, in a NATO air defense radar system, two PXI - 7853R modules were used to send commands and receive data from the radar modulator, with one unit monitoring voltage and radar triggers and the other keeping track of parameters like focus magnet currents and power supply.
