Affected by Where saved
A string that contains the name of the configuration list that the instrument will
create for this sweep
The voltage or current source level at which the sweep starts:
Current: 1 µA to 7.35 A
•
Voltage 200 mV to 105 V
•
The voltage or current at which the sweep stops:
Current: 1 µA to 7.35 A
•
Voltage 200 mV to 105 V
•
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
The delay between measurement points; default is smu.DELAY_AUTO, which
enables autodelay, or a specific delay value from 50 µs to 10 ks, or 0 for no delay
The number of times to run the sweep; default is 1:
Infinite loop: smu.INFINITE
•
Finite loop: 1 to 268,435,455
•
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
•
Complete the sweep if the source limit is exceeded: smu.OFF
Abort the sweep if the source limit is exceeded: smu.ON (default)
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
•
Indicates the reading buffer to use; the default buffers (defbuffer1 or
defbuffer2) or the name of a user-defined buffer; if no buffer is specified,
defbuffer1 is used
Default is 0; see Details
