Description
The SCXI-1142, with part number 776572-42, falls under the category of SCXI & Legacy products. This model is an 8-Channel Bessel Filter, specifically designed to be used with National Instruments E/M Series DAQ systems. The filter type, as indicated, is Bessel, known for its smooth phase response and is ideal for applications requiring minimal phase distortion.
It features 8 channels, which can operate in both multiplexed and parallel modes. This flexibility allows for efficient data acquisition and processing in various complex setups. The filter order is 8th-order, providing a higher degree of signal fidelity and accuracy.
One of the key features of the SCXI-1142 is its calibration capabilities. It is equipped with hardware designed for error elimination, supporting automatic input zeroing and the use of an external reference voltage for calibration purposes. This ensures high precision and reliability in measurements. Additionally, the module includes DC compensation to further enhance its performance.
For maintaining calibration constants, the SCXI-1142 is equipped with onboard EEPROM. This feature ensures that calibration data is preserved, facilitating easy and accurate recalibration when necessary. Despite being announced as obsolete by National Instruments, the SCXI-1142 remains available for purchase and repairs through Apex Waves, ensuring that users can continue to rely on its performance and capabilities.
