NI SCXI-1141 182610D-01 8-Channel Signal Conditioning Module

NI SCXI-1141 (Part No.182610D-01) is an 8-channel elliptic lowpass filter signal conditioning module for NI SCXI data acquisition platform. It adopts elliptic filter design with high stopband attenuation, effectively eliminating high-frequency noise and anti-aliasing interference before analog-to-digital conversion.

This module supports differential analog input and programmable cutoff frequency settings. It can be installed in standard SCXI chassis and works with NI DAQ hardware and LabVIEW software. Widely used in vibration testing, acoustic measurement and strain signal acquisition, it serves as spare parts for maintenance of legacy test systems.
