Description
The NI PXIe-4330 is a high-accuracy, bridge analog input module designed for use in various applications that require precise measurement capabilities. It features 8 analog input channels, making it ideal for multi-point data acquisition or sensor monitoring systems. Each input channel is capable of simultaneous sampling, ensuring that data from all channels are acquired concurrently without time disparity.
With an ADC resolution of 24-bits, the PXIe-4330 offers high-resolution data conversion, enabling users to capture even the most subtle changes in their measurements. This is complemented by its high throughput capability, which allows for faster data processing and reduced time to insight.
The module’s sampling mode is simultaneous, meaning that all channels are sampled at exactly the same time, ensuring synchronized data collection across all channels. This feature is particularly important in applications where timing between channels must be precisely controlled.
In terms of accuracy, the PXIe-4330 stands out with its high accuracy performance, ensuring reliable and consistent data collection even in demanding applications. This is further enhanced by its synchronization capabilities, allowing it to work seamlessly with other synchronized instruments within a system.
Each input channel is equipped with separate digital filters, providing flexibility in configuring the module to meet specific application needs and to mitigate noise in measurement signals. The module also boasts a FIFO buffer size of 1,023 samples, enabling efficient data management and reducing the likelihood of data overflow during high-speed data acquisition.
Data transfer is facilitated through both programmed I/O and direct memory access, offering flexibility in choosing the data transfer method that best suits the application’s requirements. The module supports a frequency sample rate ranging from 1 S/s to 25.6 kS/s, allowing users to select the appropriate sampling rate for their specific measurement tasks.
With a Common Mode Rejection Ratio (CMRR) of 85 dB, the PXIe-4330 effectively minimizes the influence of common-mode noise, ensuring that the measurements are
