Agilent N678xA SMU Emulation Settings
NOTE
The Source Settings window lets you access the specialized operating modes
of the Agilent Models N678xA SMU when these power modules are installed.
The Emulating dropdown list lets you access the specialized
operating modes of the Agilent Models N678xA SMU. Use the
navigation keys to select one of the emulating modes.
NOTE
Information about the Voltage Measure Only and Current Measure Only modes is
discussed in chapter 4.
4-Quadrant Power Supply
4-quadrant operation is only available on Agilent Model N6784A.
Operation is allowed in all four output quadrants. Refer to Chapter 6
under “Priority Mode Operation” for more information. 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.
NOTE
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. Refer
to chapter 6 for a detailed description of voltage and current priority.
