These commands are used to specify the start and stop levels for a sweep. If
using a fixed (manual) source range, the sweep will be performed using a
source range that will accommodate all source values (Best Fixed Range).
You can use source auto range if sweeping through one or more source
ranges.
When the sweep is started, the source will output the specified start level
and, after the delay period of the SDM cycle, a measurement is performed.
The sweep continues until the source outputs the specified stop level. At this
level, the instrument again performs another measurement (after the SDM
delay) and then stops the sweep.
The source-measure points in a sweep can be set by specifying a step size,
or by specifying the number of source-measure points in the sweep. Refer to
:STEP and :POINts.
:STARt and :STOP are coupled to :CENTer and :SPAN. Thus, when start
and stop values are changed, the values for center and span are affected as
follows:
Center = (Start + Stop) / 2
Span = Stop - Start
Specify start current level (current sweep)
Specify start voltage level (voltage sweep)
Specify stop current level (current sweep)
Specify stop voltage level (voltage sweep)
Set I-Source level (amps)
