Description
The NI SCXI-1143 Lowpass Filter Input Module, with Part Number 776572-43, is designed to deliver a high-quality, 8th-order Butterworth filter response across its eight channels. This module provides robust ±30 V overvoltage protection when powered and offers a substantial 333 kS/s maximum sampling rate for precise data acquisition.
Compatible with NI-DAQ 7 driver software, the SCXI-1143 recommends additional software such as VI Logger, LabVIEW, Measurement Studio, and LabWindows/CVI for enhanced functionality and user experience. The cutoff frequency is highly flexible, ranging from 10 Hz to 25 kHz, and can be precisely set using the formula fc = 100 kHz/n, where n can be any integer from 4 to 10,000.
Users benefit from the convenience of external clock control, ensuring that all eight channels maintain an identical cutoff frequency. Moreover, the module features a software-controlled option to bypass the filters per channel, allowing for unfiltered signals when necessary.
To operate the SCXI-1143 module, essential components include an SCXI-1304 or SCXI-1305 terminal block, an SCXI chassis or PXI/SCXI combination chassis, and an E/M Series DAQ instrument or SCXI-1600, ensuring a seamless integration into various data acquisition systems.
