About the SCXI-1141/1142/1143
This chapter describes the SCXI-1141/1142/1143 module, and explains
how to install and remove the hardware and software.
The SCXI-1141/1142/1143 module has eight lowpass filters and
eight differential-input amplifiers. The SCXI-1141 has elliptic filters;
the SCXI-1142, Bessel filters; and the SCXI-1143, Butterworth filters.
You can use the SCXI-1141/1142/1143 module for lowpass filtering and
antialiasing applications as well as for general-purpose signal amplification
and filtering. The SCXI-1141/1142/1143 module works with National
Instruments E/M Series DAQ devices. You can use one DAQ device to
control several SCXI-1141/1142/1143 modules, in combination with other
SCXI modules in a chassis. Each SCXI-1141/1142/1143 module can
multiplex its channels into a single channel of the DAQ device, although
separate outputs are also available. You can multiplex the output of several
SCXI-1141/1142/1143 modules into a single channel, thus greatly
increasing the number of analog input signals that the DAQ device can
digitize.
The SCXI-1304 shielded terminal block has screw terminals for easily
connecting signals to the SCXI-1141/1142/1143 module and is the terminal
block recommended for use with this module.

module specifications.
