Current Bias Forcing Functions/Measure Options window
The Current Bias (VMU) Function Parameters are configurable as follows:
• The Level parameter edit box specifies the SMU current to be forced, the units for that are
selected through the combo box at the right of the edit box.
• The Compliance parameter edit box specifies any valid SMU voltage compliance (or limit),
the units for which are specified through the combo box at the right of the edit box.
• The Src Range (source range) combo box specifies the SMU current range used to force
the bias current. For example, when forcing 30nA you would typically choose the 100nan
SMU range or the Best Fixed SMU range, which allows the SMU to select the most
appropriate range, based on the forcing value.
• Power On Delay: When an ITM test is run, the SMUs for the given test power-on in a
specific sequence. A power-on delay can be set between the SMUs in the test. The Power
On Delay field is used to set this delay, which can be set from 0 to 0.100 s. For details, see
Power On Delay earlier in this
• When selected, the Pulse Mode combo box allows definition of pulse on and off times, and
pulse base current. The on and off times can be set from 5 ms to 10 s. Pulse output goes to
the specified current level during the pulse on time. During the off time, pulse output returns
to the specified Base Current level. For details, see
NOTE
Understanding and configuring the Voltage Bias forcing function
The Voltage Bias forcing function maintains a selected constant-voltage state at the terminal,
subject to a user-specified current compliance of the connected SMU. A typical Voltage Bias
Forcing Functions/Measure Options window is shown in
6-104
Pulse Mode can be selected ONLY when source and measure ranges are fixed. In
other words, Pulse Mode is disabled if the source or measure range is set to AUTO.
