About Ext DC Devices

Description

Sets and returns a user-defined command string that is used to set the DC limit of the external DC source. The actual limit value is set using either the VoltageLimit (voltage) or CurrentLimit (current). The limit command is sent to the external DC source at the beginning of a sweep for each channel. The firmware automatically selects the current or voltage limit value depending on the external DC source type.
