4 Operating the Power System
For models with multiple ranges, you can select a lower range if you need better output resolution.
Front Panel Menu Reference
Press the Current key.
Select a lower range. Then press Select.
For Keysight Models N678xA SMU, N6783A, and N679xA
operating in voltage priority mode, you can specify a positive and negative 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.
For Models N678xA SMU, check Tracking to let the negative current limit track the positive current
limit. The negative current limit of Model N6783A-MFG is not programmable, but is fixed at -2A.
Front Panel Menu Reference
Press the Current key.
Specify a + Current limit and or a − Current limit. Then press
Select.
On N678xA SMU, check Tracking if you want the − limit to track
the + limit.
Set the Output Resistance
For Keysight Models N6781A and N6785A
primarily used in battery testing applications, and only applies in Voltage priority mode. Values are
programmed in Ohms, from –40 mΩ to +1 Ω.
Front Panel Menu Reference
Select Output\Settings\Resistance.
Check Enable to enable resistance programming. Enter a value.
Then press Select.
For Keysight Models N679xA
Resistance may be programmed in any of three overlapping ranges. The load module selects the
range that corresponds to the resistance value that you program.
The resistance selection must previously be selected under Output Mode.
