Sweep Operation
9-5
Figure 9-4 shows a custom sweep example with different pulse widths. In this example, the
first two points are configured with the same source value so that the duration of the first pulse
is effectively doubled.
Source memory sweep
For a source memory sweep, up to 100 setup configurations can be saved in memory. When
the sweep is performed, the setup at each memory point is recalled. This allows multiple func-
tions and math expressions to be used in a sweep. For example, the first point in a source mem-
ory sweep may source voltage and measure current, the next point may source current and
measure voltage, the third point may source voltage and measure voltage, and the last point
may use a math expression. This feature allows you to customize each sweep point with spe-
cific instrument settings instead of being tied to one set of settings for all sweep points.
Once source memory setups are saved and the sweep is initiated, the SourceMeter then
sequences through the setups very rapidly. This feature allows you to use the instrument as a
fast, automatic test sequencer.
Sweep con
fi
guration
The user specifies the number of memory location points to sweep and where to start the
sweep. For example, you can specify a six point sweep that starts at memory location 98. When
the sweep is started, the setups at memory location points 98, 99, 100, 1, 2, and 3 are recalled.
When sweeping past point 100, the sweep automatically wraps back to memory location
point 1. These and other components of the sweep are configured from the CONFIGURE
SWEEPS menu.
NOTE
These and other components of the sweep are configured from the CONFIGURE
SWEEPS menu. See “Configuring and running a sweep” later in this section.
Setups are saved in battery backed-up memory, and they remain and can be recalled
even if the SourceMeter looses external power.
NPLC caching can be used to speed up source memory sweeps. See “NPLC cach-
ing” in Section 3.
