Product details

The NI SCXI-1143 is an 8-channel low-pass Butterworth filter module designed for anti-aliasing applications. The main features and functions of the module are as follows:

Programmable gain: Each channel has programmable gain capability with input range from ±50 mV to ±5 V, which allows the user to adjust the amplitude of the signal as needed.

Programmable filter Settings: This module provides an 8-order programmable low-pass filter that allows the user to set the cut-off frequency of the filter, ranging from 10 Hz to 25 kHz.

High sampling rate: The SCXI-1143 supports a sampling rate of up to 333 kS/s (thousand samples per second), maintaining efficient data acquisition speed regardless of the gain setting.

Flexible filter types: Users can choose between elliptical filter, Bessel filter or Butterworth filter types to meet different application requirements.

Channel independence: Although all channels must be set to the same cutoff frequency, each channel can be independently programmed to bypass the low-pass filter, increasing the flexibility of use.

Hybrid filter technology: The module combines analog and switched capacitor filters (SCFs) to provide 10,000 discrete, software-programmable cutoff frequencies while maintaining the low-noise performance of traditional continuous-time active filters.

External clock input and output: The module provides external clock input and output functions that allow users to use an external clock in tracking filter applications to set the cut-off frequency of the filter.

Signal conditioning: The module is capable of conditioning signals ranging from ±50 mV to ±5 V, making it suitable for a variety of application scenarios.

Operation mode: SCXI-1143 supports both multiplexing and parallel operation modes to meet the needs of different data acquisition and processing.

In addition, if filtering and sampling are required at the same time, users can cascade the SCXI-1143 with the SCXI-1140 for a higher level of data acquisition and filtering capabilities.

In summary, the NI SCXI-1143 8-channel low-pass Butterworth filter module is a powerful and flexible data acquisition device for a variety of applications requiring accurate filtering and signal conditioning.
