Understanding and configuring the Voltage Step forcing function
The Voltage Step forcing function increments through a multiple evenly spaced, constant voltage
steps over a user-specified range, subject to a user-specified current compliance. The time
interval for each step is determined automatically by the time required to complete a sweep. A
typical Voltage Step Forcing Functions/Measure Options window is shown in
Figure 6-145

The Voltage Step Function Parameters are configurable in essentially the same way as the
Current Sweep Step Parameters, as follows:
4200-901-01 Rev. S / May 2017
- The Best Fixed option commands the SMU to automatically select the single current
range that best fits the entire step range.
- The numerical current range options allow you to manually select an SMU range to suit
your needs.
• Compliance: The Compliance parameter edit box specifies any valid SMU voltage
compliance limit, the units for which are selected through the combo box at the right of the
edit box.
• Start: The Start edit box specifies the voltage forced for the first step value. The Start
parameter may be any valid SMU voltage, the units for which are selected through the
combo box at the right of the edit box.
• Stop: The Stop edit box determines the voltage forced for the last step value. The Stop
parameter may be any valid SMU voltage, the units for which are selected through the
combo box at the right of the edit box.
• Step: The Step edit box specifies the voltage step increments and determines the Data
Points value {Data points value = integer value of [1 + (Stop value - Start value)/(Step
value)].
The Step parameter may be any valid SMU voltage value, the units for which are selected
through the combo box at the right of the edit box. However, note the following:
