<function>
The source function:
• CURRent
•
VOLTage
<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 -1, 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: 0
• 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: AUTO
• Best fixed range: BEST (default)
•
Present source range for the entire sweep: FIXed
<failAbort>
Abort the sweep if the source limit is exceeded: ON (default)
Complete the sweep if the source limit is exceeded:
OFF
<dual>
Determines if the sweep runs from start to stop and then from stop to start:
• Sweep from start to stop only: OFF (default)
• Sweep from start to stop, then stop to start:
ON
