About the SCXI-1125
This chapter introduces the SCXI-1125 module and explains how to install
the software and hardware.
the software and hardware.
The SCXI-1125 is an eight-channel isolated analog input conditioning
module with programmable gain and filter settings on each channel and
is jumperless. Each channel has 12 programmable gain settings from
1 to 2000 and two programmable filter settings of either 4 Hz or 10 kHz.
Each channel has an external circuit for grounding the inputs that you can
use for offset calibration. An onboard EEPROM provides nonvolatile
storage of software correction constants for both gain and offset.

The SCXI-1125 provides up to 300 V
rms
working isolation per channel and
has an input range of up to 1000 VDC when using an appropriate attenuator
terminal block. The SCXI-1125 supports both multiplexed and parallel
output modes and includes a cold-junction compensation (CJC) channel
that you can scan in multiplexed mode.
