SCXI-1520 Module
The SCXI-1520 is an 8-channel module used to interface with strain gauges
and strain-gauge-based sensors.
You can set the bridge excitation voltage, hardware null setting, filter cutoff
frequency, or shunt calibration settings on a per-channel basis through
software control. You can set the gain of each input channel through
LabVIEW or NI-DAQ. An onboard EEPROM contains gain and offset
calibration constants for each channel. NI-DAQ and LabVIEW
automatically use these constants to correct for amplifier gain and offset
errors when scaling data.

Jumper Description Configuration
Parking position. Use this setting with DAQ
devices in DIFF mode (factory-default
position).
Use this position for DAQ devices with SE
inputs, such as the Lab and 1200 devices,
DAQCard-700, or MIO and AI devices in
RSE mode.
Connects the SCXIbus guard to the analog
reference.
Select this position for MIO and AI devices
in NRSE mode.
