NI SCXI-1141 is an 8-channel elliptic lowpass filter module designed for noise reduction and anti-aliasing in data acquisition systems. Featuring programmable cutoff frequencies (4 Hz to 10 kHz) and high stopband attenuation, it ensures clean signal acquisition for dynamic measurements. Compatible with SCXI chassis, it is ideal for vibration analysis, audio testing, and sensor signal conditioning in industrial and research applications.
Product Specifications
Key Specifications & Capabilities
8-Channel Elliptic Lowpass Filter – Provides sharp roll-off and high stopband attenuation for effective noise suppression.
Programmable Cutoff Frequencies – Selectable ranges (4 Hz, 10 Hz, 100 Hz, 1 kHz, 10 kHz) to match signal bandwidth requirements.
High Signal Integrity – >80 dB attenuation in the stopband minimizes aliasing and out-of-band noise.
Low Distortion & Phase Shift – Maintains signal accuracy for dynamic and transient measurements.
Differential Inputs – Reduces common-mode noise for high-precision signal conditioning.
Compatibility – Works with NI SCXI chassis and LabVIEW/DAQmx for seamless integration into automated test systems.
Applications – Optimized for vibration analysis, audio testing, strain gauges, and biomedical signal processing.
