Description
The SCXI-1141 is a highly specialized module with a part number of 776572-41. It is designed to operate as an 8-Channel Programmable Elliptic Lowpass Filter, making it a versatile choice for a variety of signal processing applications. The elliptic lowpass filter type is known for its sharp cutoff characteristics, providing an attenuation rate of 135 dB/octave. This allows for precise filtering of unwanted frequencies from the signal.
Each channel is equipped with differential-input amplifiers, ensuring that the module can handle a wide range of signal types with high fidelity. The SCXI-1141 is capable of a sampling rate of up to 333 kS/s, making it suitable for high-speed data acquisition tasks. Its compatibility with National Instruments E/M Series DAQ instruments allows for seamless integration into existing systems.
To facilitate a variety of signal connections, the SCXI-1141 recommends using either the SCXI-1304 or SCXI-1305 Shielded Terminal Blocks. These terminal blocks are designed to maintain signal integrity and reduce noise in measurement setups. The module supports both AC or DC coupling, as well as floating or ground-referenced signals, offering flexibility in signal conditioning applications.
One of the key features of the SCXI-1141 is its ability to provide software programmable cut-off frequencies, with up to 10,000 discrete options. This feature, combined with an external clock input/output and an auto-zero mode, enhances the module’s precision and adaptability. The included NI-DAQmx driver software ensures easy integration and compatibility with application development environments (ADEs) like LabVIEW and LabWindows/CVI, further extending its utility in various applications.
