Section 5: Sweep Operation Series 2600 System SourceMeter® Instruments Reference Manual
When this sweep starts, the output will go to the start level (1V) and sweep through the
symmetrical log points. The time duration before each measurement at each step is determined by
the measurement delay interval.
Pulse sweeps
A fixed pulse sweep outputs fixed voltage or current pulses. Programmable parameters with this
function include the sourcing function, the bias level, the pulse level, the number of pulses, the
pulse on time, the pulse off time, and which SourceMeter channel is used (A or B).
When this sweep executes, the output will go from the bias level to the “on” level of the first pulse.
The time duration at each pulse level is determined by the programmed on time while the period
between pulses is determined by the programmed off time.
An example of a simple three-point pulse sweep is shown in Figure 5-4. Note that the programmed
pulse on time determines the pulse width, and the pulse off time is the time between pulses. The
level is the same for each pulse. Refer to
Section 13 for more KIPulse information and more
detailed information on KIGeneral.

Custom (list) sweeps
This sweep type lets you configure a customized sweep with arbitrary steps. Programmable
parameters include the source function, channel, list of sweep values, delay (settling time), and
the number of points.
When this sweep is started, the output level goes to the first point in the sweep. The sweep will
continue through the steps in the order they were programmed and stop after the last step. The
time duration before the measurement at each step is determined by the delay interval (settling
time).
Figure 5-5 shows an example of a custom sweep with six measurement points. When the sweep
starts, the current or voltage goes to the first point in the sweep. The unit cycles through the sweep
points in the programmed order.
