First-Stage
Second-Stage
The order of the settings for the first- and second-stage gain does not matter
as long as the first-stage gain multiplied by the second-stage gain equals the
desired final gain value.
Configuring the Filter Jumpers
Each input channel also has two user-configurable filter stages.
The SCXI-1121 module ships in the 4 Hz position. Refer to Table 4 to find
the correct jumper setting for the desired cutoff frequency. Figure 3 shows
the locations of the jumper blocks on the SCXI-1121 module. Verify that
both filter stages are set to the same filter setting to ensure that you achieve
the desired bandwidth.
