Automatic Abort Function
Automatic Abort Function
The automatic abort function stops measurement (increasing or decreasing source
output value) when one of the following conditions occurs. This function is useful to
reduce sweep time and to prevent damage to the device during measurement.
• The output reaches voltage compliance or current compliance
• A measurement value exceeds the specified measurement range
• An SMU oscillates, or an error is caused in the CMU
The automatic abort function is enabled by the following commands.
• WM: Staircase sweep, staircase sweep with pulsed bias, multi channel sweep,
and pulsed sweep measurements
• BSM: Binary search measurement
• LSM: Linear search measurement
• MSC: Sampling measurement and C-t sampling measurement
• QSM: Quasi-static CV measurement
• WMDCV: CV (DC bias) sweep measurement
• WMFC: C-f sweep measurement
• WMACV: CV (AC level) sweep measurement
When abort occurs After measurement is aborted, the source forces the following value. And then the
dummy data (199.999E+99) is returned for measurement points not reached.
• Start value (for sweep source and search output source)
• Pulse base value (for pulsed source and pulsed sweep source)
• Base value (for synchronous source of sampling measurement)
Output after
measurement
The commands listed above also can be used to set the source output after the
measurement ends normally. The source output value can be one of the following
values.
• Sweep measurement: Start value or stop value
• Search measurement: Start value, stop value, or last output value
• Sampling measurement: Base value or bias value
