National Instruments SCXI-1141 Lowpass Filter Input Module

The SCXI-1141 (Part Number: 776572-41) has eight lowpass elliptic filters and eight differential-input amplifiers. This Lowpass Filter Input Module can be utilized for lowpass filtering and antialiasing applications, along with general-purpose signal amplification and filtering. This module is also suggested for sharp filter roll off. All eight channels must be set to an identical cut-off frequency, but the user can programmatically bypass the lowpass filter for each channel. The device has a sampling rate of up to 333 kS/s, and an attenuation rate of 135 dB/octave. The NI SCXI-1141 will function with National Instruments E/M Series DAQ instruments. One DAQ instrument can be utilized to control a few SCXI-1141 modules combined with other SCXI modules in a chassis.

The SCXI-1304 and SCXI-1305 Shielded Terminal Blocks have screw terminals to effortlessly link signals to the SCXI-1141 module. The SCXI-1304 and SCXI-1305 are the advised terminal blocks to be used with this module. These terminal blocks have all the required circuitry for AC or DC coupling, as well as for floating or ground-referenced signals.

With the NI SCXI-1141 Lowpass Filter Input Module, it is possible to utilize analog filters and switched capacitor filters to attain the versatility of 10,000 discrete software-programmable cut-off frequencies, while upholding the low-noise performance of regular, ongoing time-active filters. This module additionally has an external clock input and output to allow the user to set the filter cut-off frequency with an external clock in tracking filter applications.

Designating the Auto-zero mode to One will help enhance the preciseness of measurements. When auto-zero is activated, the inputs of the SCXI-1141 module are internally grounded. The driver completes a measurement when the task starts, then subtracts the measured offset from all upcoming measurements.

The SCXI-1141 is run using the NI-DAQmx driver software which is compatible with software packages or application development environments (ADEs) such as LabVIEW or LabWindows/CVI. It can be configured using the Measurement & Automation Explorer (MAX) tool. The NI device measures 1.2 x 6.8 x 8.0 in. in physical dimensions.

SCXI-1141 Obsolete Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
