NI PXIe-8840 | PXI Express Embedded Controller

The NI PXIe-8840, as an embedded controller for PXI Express, provides powerful computing and control capabilities for PXI systems.

· Usually equipped with high-performance multi-core processors, such as Intel Xeon processors. These processors have multiple cores and high clock frequencies, capable 

of processing multiple tasks simultaneously, and can achieve complex computing and data processing functions, such as real-time analysis of large amounts of data, signal 

processing, algorithm operations, etc.

· The processor has powerful performance and can meet applications that require high computing performance, such as processing signals from multiple sensors in real-time 

control systems or quickly processing and analyzing large amounts of data in data intensive applications.

· Can provide larger memory capacity, such as 16GB, 32GB or higher, depending on different configurations. Adequate memory can ensure that the system can run multiple 

software programs and process large amounts of data simultaneously without lagging, and performs well in data collection and analysis tasks that require processing large 

datasets.

· The memory type may be high-speed DDR4 or higher to improve data read and write speed, reduce data processing latency, and enhance system response speed.

· Generally, there are multiple storage options available, including high-capacity hard disk drives (HDD) or high-speed solid state drives (SSD). Hard disk drives can provide a 

large amount of storage space for storing operating systems, applications, test data, and other files; Solid state drives can significantly improve the read and write speed of 

data, reduce system startup time and data loading time, and make the system respond more quickly.

· The storage capacity can be expanded according to user needs to meet different storage requirements in different application scenarios, such as long-term data storage 

and backup, or frequent data read and write operations.

· Having multiple Ethernet interfaces, it supports high-speed Ethernet communication, typically at 10/100/1000Mbps or higher, facilitating data exchange and remote control 

with external devices or networks. It is suitable for building distributed testing systems or implementing remote monitoring and management.

· Contains multiple USB interfaces, including USB 2.0 and USB 3.0 interfaces. The USB 3.0 interface has a higher transfer speed and can be used to connect high-speed external 

devices such as external storage devices, high-speed data acquisition devices, printers, keyboards, mice, etc.

· Equipped with multiple PXIe expansion slots, it can expand various PXIe modules such as data acquisition module, signal generator module, oscilloscope module, etc. Users 

can flexibly add the required modules according to specific testing and measurement needs to expand the system's functions.

· The number and type of expansion slots will vary depending on the specifications of the chassis, which can meet testing and measurement applications of different levels of 

complexity, enabling the system to expand from a simple signal acquisition and analysis system to a multifunctional testing platform.

· In the field of electronic device testing, it can serve as a core controller to integrate various testing equipment and instruments together. For example, when combined with a 

data acquisition card, it can accurately measure parameters such as voltage, current, and frequency in electronic circuits; Combined with the oscilloscope module, it can 

analyze the waveform, amplitude, frequency, and other aspects of the signal; Combined with the signal generator module, various test signals can be generated to form a 

complete electronic device testing system, which is used to test the performance and functionality of circuit boards, integrated circuits, sensors, etc.

· In communication equipment testing, multiple testing modules can be coordinated to test and analyze communication signals, including measuring the modulation and 

demodulation characteristics, frequency range, power, bandwidth and other parameters of the signals, evaluating the performance and diagnosing faults of communication 

equipment, and ensuring that the performance of communication equipment meets standards.

And characteristics; Simulation and data processing can be carried out in physics experiments; Can process biological signals in biological experiments.
