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. The SCXI-1121 ships with the first-stage gain
set to 100 (position A) and the second-stage gain set to 10 (position D).
To change the gain setting of a specified channel on the SCXI-1121, refer
to Table 3 for the gain jumper reference designators. Refer to Figure 3 for
the location of the gain jumpers. Move the jumper to the position indicated
in Table 4.
