10.5 Source Subsystem

This subsystem programs all the output parameters of the RP Series AC source.

[SOURce:]CURRent
This command sets the rms current limit of the output. If the load current exceeds the
programmed current limit, the unit responds in one of two ways, depending on the current
limit mode that is configured (hardware configuration only). In the default constant current
mode, the output voltage will fold back as much as needed to retain the current at the
programmed limit. No error message is generated when operating in this mode. If constant
voltage mode is configured instead, the output latches into a disabled state when current
limiting occurs. The output voltage is set to 5.0 volt when this condition occurs and the
output relay state is set to 0 (output relay open). A " 300, Device specific error" fault is
generated.
Note that the CURRent command is coupled with the VRANGe. This means that the
maximum current limit that can be programmed at a given time depends on the voltage
range setting in which the unit is presently operating.
