Front Panel:
Press the Current key.
Enter a value and press Select.
For models with multiple ranges, you can select a lower range if you
need better output resolution.
Front Panel:
Press the Current key.
Select a lower range and press
Select.
For Agilent Models N678xA SMU operating in voltage priority mode,
you can specify a Current limit., which limits the output current at
the specified value. In voltage priority mode, the output voltage
remains at its programmed setting as long as the load current is
within the positive or negative limit. Check Tracking to let the
negative current limit track the positive current limit setting.
Front Panel:
Press the Current key.
Specify a + Current limit and or a
− Current limit and press Select.
Check the Tracking box if you want
the − limit to track the + limit.
This information applies to Agilent Models N678xA SMU only.
For Agilent Models N678xA SMU, you can select either Voltage
priority or Current priority mode.
In voltage priority mode the output is controlled by a bi-polar
constant voltage feedback loop, which maintains the output voltage
at its positive or negative programmed setting. The output voltage
will remain at its programmed setting as long as the load current
remains within the positive or negative current limit.
In current priority mode the output is controlled by a bi-polar
constant current feedback loop, which maintains the output sourcing
or sinking current at its programmed setting. The output current will
remain at its programmed setting as long as the load voltage remains
within the positive or negative voltage limit.
