Keysight N678xA Multi-Quadrant Operation
Keysight Models N678xA SMU can be operated in either voltage or
current priority mode. They can source as well as sink output power.
Note that Keysight Models N6781A, N6782A, N6785A, and N6786A
operate only in the + Voltage quadrants.
Voltage Priority Mode
In voltage priority mode, the output voltage should be programmed to
the desired positive or negative value. A positive current limit value
should also be set. The current limit should always be set higher than
the actual output current requirement of the external load. With tracking
enabled, the negative current limit tracks the positive current limit
setting. With tracking disabled, you can set different values for the
positive and negative current limits.
The following figure shows the voltage priority operating locus of the
power modules. The area in the white quadrants shows the output as a
source (sourcing power). The area in the shaded quadrants shows the
output as a load (sinking power).

The heavy solid line illustrates the locus of possible operating points as a
function of the output load. As shown by the horizontal portion of the
line, the output voltage remains regulated at its programmed setting as
long as the load current remains within the positive or negative current
limit setting. A CV (constant voltage) status flag indicates that the output
current is within the limit settings.
