User’s Manual Sweep Operation 10-13
• SOURCE RANGING — Use this menu item to control source ranging
(ignored in source memory):
– BEST FIXED — With this option, the SourceMeter will select a single
fixed source range that will accommodate all of the source levels in the
sweep. For example, if the minimum and maximum source levels in the
sweep for the Model 2400 are 1V and 30V, the 200V source range will
be used.
– AUTO RANGE — With this option, the SourceMeter will select the most
sensitive source range for each source level in the sweep. For exam
-
ple, for a 1V source level, the 2V source range will be used, and for a
3V source level, the 20V source range will be used. Note that the range
changing process of AUTO RANGE may cause transients in the
sweep. If these transients cannot be tolerated, use the BEST FIXED
source range.
– FIXED — With this option, the source remains on the range presently
on when the sweep is started. For sweep points that exceed the source
range capability, the source will output the maximum level for that
range. For example, if the source is on the 2V range when the sweep is
started, it will remain on the 2V range for the entire sweep. If the config
-
ured sweep points are 1V, 2V, 3V, 4V, and 5V, the sweep will be 1V, 2V,
2.1V, 2.1V, and 2.1V.
• COMPLIANCE ABORT — Use this option to control abort on compliance,
which will abort a sweep in progress if compliance is detected:
– NEVER — This selection disables abort on compliance.
– EARLY — Abort sweep if compliance is detected at the beginning of
the SDM cycle.
– LATE — Abort sweep if compliance is detected at the end of the SDM
cycle.
