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.
