If the source is a SMU, the source mode for the sweep can be voltage or current. If, however, a
voltage source (VS1...Sn) is used, the source mode must be voltage.
You can do the sweep on a linear or logarithmic scale. With the linear sweep mode selected, the
start, stop, and step value parameters define the sweep. Each VAR1 sweep in the figure above
sweeps from 1 V (start) to 5 V (stop) in 1 V steps.
With a logarithmic sweep mode selected (log base 10, 25, or 50), only specify the start and stop
values. Step size is automatically set to provide a symmetrical sweep on the logarithmic scale.
The time spent on each sweep step depends on the user-set delay time and the time it takes to
perform the measurement.
You can delay the start of the sweep by setting a hold time.
Example
This command string sets up a VAR1 linear sweep with a start = 1 V, stop = 5 V, step = 1 V, and
compliance = 10 mA.
The following figure shows the sweep that results from this setup. The figure in the Details shows the
results of the same setup when used with a VAR2 step command.
