Dual Sweep
When you select Dual Sweep, the instrument sweeps from start to stop, then from stop to start. When
you clear Dual Sweep, the instrument sweeps from start to stop only.
The following figure compares a single sweep to a dual sweep.

Points (list sweep)
The number of sweep points that were defined in the List Values list. This number is automatically
generated.
Force Range (Source Range)
The SMU range that is used when forcing the voltage or current.
You can select:
• Best Fixed: The instrument selects a single fixed source range that will accommodate all the
source levels in the test.
• Auto: The instrument selects the most sensitive source range for each source level in the test.
This option provides the best resolution and control when sweeping or stepping several decades.
However, the range changes can reduce speed.
• Specific range: Select one of the listed ranges. The source remains on the range that is set. If
you are sweeping and a sweep point exceeds the source range capability, the source outputs the
maximum level for that range. This range must be equal to or greater than the largest value in the
sweep.
