SCXI-1120/D Calibration Procedure
Figure 2.
Side Plate Removal and Module Installation
The SCXI-1120/D module does not need to be connected to a data
acquisition (DAQ) device. Leave the configuration of the digital jumpers
W41–W43 and W46 unchanged because they do not affect this procedure.
Configuring the Gain Jumpers
Each input channel has two user-configurable gain stages. The first-stage
gain provides gains of 1, 10, 50, and 100. The second-stage gain provides
gains of 1, 2, 5, 10, and 20. Table 1 shows the jumper reference designators
for gain selection associated with each channel. Table 2 shows how to
position each jumper to select the desired gain for each channel.
