Excitation Level
Each excitation channel of your SCXI-1121 has two different current or
voltage levels. You can set a given channel to one of the following level
modes:
• In the Current mode
• In the Voltage mode
It is important to notice that you should select the level of excitation
according to the load you are using. Table 2-7 lists the maximum load that
can be driven per channel at each level of excitation for both volt and
current excitation.
