<function>
The source function:
•
CURRent
•
VOLTage
<start>
The voltage or current source level at which the sweep starts:
•
Current: 1 µA to 7.35 A
•
Voltage: 200 mV to 105 V
<stop>
The voltage or current at which the sweep stops:
•
Current: 1 µA to 7.35 A
•
Voltage: 200 mV 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
<delay>
The delay between measurement points; default is
-1
, which enables autodelay, or
a specific delay value from 50
µ
s 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
<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
