Details
This command sets the output level of the voltage or current source. If the output is on, the new level is sourced
immediately.
The sign of the source level dictates the polarity of the source. Positive values generate positive voltage or
current from the high terminal of the source relative to the low terminal. Negative values generate negative
voltage or current from the high terminal of the source relative to the low terminal.
If a manual source range is selected, the level cannot exceed the specified range. For example, if the voltage
source is on the 2 V range (auto range is disabled), you cannot set the voltage source amplitude to 3 V. When
auto range is selected, the amplitude can be set to any level.
Example
smu.source.func = smu.FUNC_DC_VOLTAGE
smu.source.level = 1
Set the instrument to source
voltage and set it to source 1 V.
