<function>
The source function:
CURRent
VOLTage
<start>
The voltage or current source level at which the sweep starts:
Current: 1 pA to 1.05 A
Voltage: 1 pV to 1100 V
<stop>
The voltage or current at which the sweep stops:
Current: 1 pA to 1.05 A
Voltage: 1 pV to 1100 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
<delay>
The delay between measurement points; default is
-1
, which enables autodelay, or
a specific delay value from 50 μs to 10,000 s, 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
