Overview
Section overview
Following a brief “Sweep overview” of the types of sweeps (linear staircase,
logarithmic staircase, custom, and pulse), the documentation in this section
provides detailed information on characteristics, commands, and programming for
each type of sweep as follows:
• Sweep overview
• Sweep characteristics
• Sweep functions
• Running sweeps
Sweep overview
As shown in Figure 5-1, the Series 2600 SourceMeter can generate several types
of sweeps using the factory sweep scripts.
Linear staircase sweep – With this sweep type, the voltage or current increases
or decreases in specific steps, beginning with a start current and ending with a
stop current.
Figure 5-1A shows an increasing linear staircase sweep.
Logarithmic staircase sweep – In this case, the current or voltage increases or
decreases logarithmically, beginning with a start voltage or current and ending
with a stop voltage or current. Figure 5-1B shows an increasing logarithmic
staircase sweep.
Custom (list) sweep – The custom sweep allows you to program arbitrary sweep
steps anywhere within the output voltage or current range of the Series 2600.
Figure 5-1C shows a typical custom sweep with arbitrary steps.
Pulse sweeps – Two sweeps can also be performed as a pulse sweep: fixed
current pulse or fixed voltage pulse. These pulse sweeps are similar to those
outlined above except that a pulse of a specific width is generated at each point
instead of a constant level.
