Description
The NI PXIe-4330 is a high-performance, 8-channel bridge analog input module designed for use in SC Express systems. This module, identified by part numbers 781346-01 and 194953D-02L, offers exceptional accuracy and throughput for demanding applications.
With a 24-bit ADC resolution, the PXIe-4330 captures high-fidelity data from each of its 8 analog input channels. These channels are capable of simultaneous sampling, ensuring precise synchronization of data across all inputs. The module supports a high throughput rate, complemented by its high accuracy levels, to meet the needs of rigorous measurement tasks.
One of the standout features of the PXIe-4330 is its synchronization capabilities, allowing seamless integration with other modules in a measurement system. Additionally, it is equipped with digital filters on a per-channel basis, enhancing the signal quality by reducing noise and improving signal-to-noise ratios.
The module boasts a 1,023-sample FIFO buffer size, facilitating efficient data transfer via both Programmed I/O and DMA methods. This ensures a smooth and reliable data flow, even at high data rates. Speaking of rates, the PXIe-4330 supports a flexible frequency sample rate ranging from 1 S/s to 25.6 kS/s, adjustable in precise increments to suit various measurement requirements.
With a Common-Mode Rejection Ratio (CMRR) of 85 dB, the module effectively minimizes noise and interference from common-mode signals, ensuring the integrity of measurement data. It supports full, half, and quarter bridge completion modes, offering versatility in connecting different types of sensors.
The PXIe-4330’s shunt calibration is software selectable per channel, with options for 33.333 kΩ, 50 kΩ, and 100 kΩ shunt calibration values. This feature allows for easy and accurate calibration
