rangeType)
smu.source.sweeplinear(configListName, start, stop, points, sDelay, count,
rangeType, failAbort)
smu.source.sweeplinear(configListName, start, stop, points, sDelay, count,
rangeType, failAbort, dual)
smu.source.sweeplinear(configListName, start, stop, points, sDelay, count,
rangeType, failAbort, dual, bufferName)
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: -7.35 A to 7.35 A
•
Voltage: -105 V to 105 V
stop
The voltage or current at which the sweep stops:
• Current: -7.35 A to 7.35 A
•
Voltage: -105 V to 105 V
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
sDelay
The delay between measurement points; default is smu.DELAY_AUTO, which
enables autodelay, or a specific delay value from 50
µ
s to 10 ks, 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 268,435,455
rangeType
The source range that is used for the sweep:
• Most sensitive source range for each source level in the sweep:
smu.RANGE_AUTO
• Best fixed range: smu.RANGE_BEST (default)
• Present source range for the entire sweep:
smu.RANGE_FIXED
failAbort
Complete the sweep if the source limit is exceeded: smu.OFF
Abort the sweep if the source limit is exceeded:
smu.ON
(default)
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
