SCXI-1121 Calibration Procedure
Configuring the Excitation Level
Each excitation channel of the SCXI-1121 module has two different current
or voltage levels. You can set a given channel to one of the following level
modes:
• In the current mode—0.150 or 0.450 mA
• In the voltage mode—3.333 or 10 V
After selecting the excitation mode of operation desired—voltage or
current—as described in the previous section, refer to Table 6 to set the
SCXI-1121 module for the level of operation. The SCXI-1121 module
ships with the voltage mode set to 3.333 V.
