Description A sweep can be configured by specifying center and span parame-
ters. By specifying a center point, you can sweep through the operat-
ing point of a device. The span determines the sweep width with the
operating point at the center of the sweep.
For example, assume you are testing a device that operates at 10V,
and you want to sweep from 8 to 12 volts. To do this, you would
specify the center to be 10V and the span to be 4 volts (12 - 8).
Use the :STEP or :POINts command to specify the number of
source-measure points in the sweep.
:CENTer and :SPAN are coupled to :STARt and :STOP. Thus,
when center and span values are changed, the values for start and
stop are affected as follows:
Start = Center - (Span / 2)
Stop = Center + (Span / 2)
STEP <n>
:SOURce[1]:CURRent:STEP <n> Specify step size (current sweep)
:SOURce[1]:VOLTage:STEP <n> Specify step size (voltage sweep)
