Description
The National Instruments SCXI-1141 Lowpass Filter Input Module, part number 776572-41, falls under the SCXI & Legacy category. This module is specifically designed to cater to applications requiring lowpass elliptic filters and features differential-input amplifiers for enhanced signal integrity.
It supports 8 channels, allowing for multiple signal inputs, and boasts a high sampling rate of up to 333 kS/s. One of its remarkable features is the steep attenuation rate of 135 dB/octave, ensuring precise filtering of unwanted frequencies. The SCXI-1141 is compatible with National Instruments E/M Series DAQ instruments, making it a versatile choice for a wide range of data acquisition systems.
For optimal performance, it is recommended to use the SCXI-1304 or SCXI-1305 Shielded Terminal Blocks. These terminal blocks are designed to minimize noise and ensure stable connections. The module also offers 10,000 discrete software-programmable cut-off frequencies, providing flexibility in filtering applications. Additionally, the inclusion of an external clock input/output feature enhances its ability to synchronize with other devices.
An auto-zero mode is available to compensate for DC offset, ensuring accurate measurements over time. The module is supported by NI-DAQmx driver software, facilitating easy integration and configuration within your system. Lastly, its physical dimensions are 1.2 x 6.8 x 8 inches, making it compact and easy to fit into various setups.
