Overview

Product overview

Key product information and technical features.

The SCXI-1143 provides eight channels of Butterworth low-pass filtering. Its filter response distinguishes it from the SCXI-1142 Bessel filter module and the SCXI-1141 elliptic filter module.

In NI's documented cascaded systems, the SCXI-1143 can serve as a programmable filtering stage following selected isolation modules. Supported combinations depend on the upstream module, connected DAQ device, and driver; the module name alone does not establish complete system compatibility.

Software reference

NI-DAQmx 18.6 lists the SCXI-1143 among supported SCXI modules; this is version-specific evidence, not a claim of support in every driver release.

Select an SCXI system configuration; verify the chassis, DAQ device, cabling, and driver together before integration.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

What filter response does the SCXI-1143 provide?

The SCXI-1143 provides Butterworth low-pass filtering across eight channels. It is not the Bessel variant; that model is the SCXI-1142.

Does NI-DAQmx support the SCXI-1143?

NI-DAQmx 18.6 explicitly lists the SCXI-1143 as supported hardware. Check the readme for the exact driver release and operating system intended for your system rather than assuming support across all versions.

Can the SCXI-1143 be cascaded with an SCXI-1140?

NI documents that combination for simultaneous filtering with E Series DAQ devices under Traditional DAQ only. It is listed as partially supported, with measurement-accuracy limitations described in NI's cascading guide.
