configListName
A string that contains the name of the configuration list that the instrument will
create for this sweep
start
The voltage or current source level at which the sweep starts:
• Current: 1 pA to 1.05
•
Voltage: 1 pV to 210
stop
The voltage or current at which the sweep stops:
• Current: 1 pA to 1.05
•
Voltage: 1 pV to 210
points
The number of source-measure points between the start and stop values of the
sweep (2 to 1e6); to calculate the number of source-
measure points in a sweep, use
the following formula:
Points = [(Stop - Start) / Step] + 1
delay
The delay between measurement points; default is smu.DELAY_AUTO, which
enables autodelay, or a specific delay value from 50 µs to 10,000 seconds, or 0 for
no delay
count
The number of times to run the sweep; default is 1:
• Infinite loop: smu.INFINITE
• Finite loop:
1
to
268435455
rangeType
The source range that is used for the sweep:
• Most sensitive source range for each source level in the sweep:
smu.RANGE_AUTO or 0
• Best fixed range: smu.RANGE_BEST or 2 (default)
Present source range for the entire sweep: smu.RANGE_FIXED or 1
failAbort
Abort the sweep if the source limit is exceeded: smu.ON (default)
Complete the sweep if the source limit is exceeded: smu.OFF
dual
Determines if the sweep runs from start to stop and then from stop to start:
• Sweep from start to stop only: smu.OFF (default)
• Sweep from start to stop, then stop to start: smu.ON
bufferName
The name of a reading buffer; the default buffers (defbuffer1 or defbuffer2) or
the name of a user-
defined buffer; if no buffer is specified, this parameter defaults to
defbuffer1
