Depending on the priority mode, you can specify either the output Voltage or output Current setting.
The Range function lets you select the appropriate output range. You can also specify a Voltage Limit
or Current Limit, which limits the selected parameter 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. In current priority mode, the output current remains at its programmed setting as
long as the output voltage is within the positive or negative limit.
Tracking Limits - lets the negative voltage or current limit track the positive voltage or current limit
setting. By default, the negative limit will track the positive limit value. Un-check this box if you want to
program asymmetrical positive and negative limits. If asymmetrical limits are programmed and
tracking is turned on, the negative value is changed to track the positive limit.
2-Quadrant Power Supply
This operating mode is restricted to two quadrants (+V/+I and +V/-I). The following figures show the 2-
quadrant settings.
Operating in – selects either Voltage Priority or Current Priority. The other settings in 2-quadrant
mode are the same as the settings in 4-quadrant mode except that you cannot program negative
voltages or negative voltage limits. Because of this, voltage tracking is not available in Current Priority
mode. Note that the negative voltage limit is fixed at –10 mV. Refer to
N678xA Multi-Quadrant
Operation for a detailed description of voltage and current priority.
Resistance - This is only available on Keysight Models N6781A and N6785A. Output resistance
programming is primarily used in battery emulation applications, and only applies in Voltage Priority
mode. Values are programmed in Ohms, from –40 mΩ to +1 Ω.
1-Quadrant Power Supply (unipolar)
This mode emulates a typical one quadrant or unipolar power supply with limited down-programming.
The following figures show the 1-quadrant settings. The Voltage Priority and Current Priority
selections determine which controls are displayed.
In 1-quadrant mode you cannot program negative voltages, negative currents, negative voltage
limits, or negative current limits. Because of this, voltage tracking and current tracking are not
available. Note that there is limited 2-quadrant operation with the negative current limit being fixed at
10% to 20% of the output current rating.
