N678xA SMU Source Functions

The Source Settings window lets you access the specialized operating modes of the
Keysight N678xA SMU modules when these power modules are installed.
The Emulating dropdown list lets you access the specialized operating modes of the Keysight N678xA
SMU. Use the navigation keys to select one of the emulating modes.
Information about the Voltage Measure Only and Current Measure Only modes is
discussed under
4-Quadrant Power Supply
4-quadrant operation is only available on Keysight N6784A. Operation is allowed in all four output
quadrants. The following figures show the 4-quadrant settings.
Operating in – selects either Voltage Priority or Current Priority. In voltage priority the output is
controlled by a bi-polar constant voltage feedback loop, which maintains the output voltage at its
positive or negative setting. In current priority the output is controlled by a bi-polar constant current
feedback loop, which maintains the output source or sink current at its programmed setting. Refer to
N678xA Multi-Quadrant Operation
When switching between Voltage Priority and Current Priority, the output is turned off
and the output settings revert to their Power-on or RST values.
