Sweep Operation
•
SWEEP COUNT – Use this menu item to specify how many sweeps to perform:
-
FINITE – Use this option to enter a discrete number of sweeps to perform with the
results stored in the data store buffer. The maximum number of finite sweeps that
can be performed is determined as follows:
maximum finite sweep count = 2500 / # Points in sweep
-
INFINITE – Select this option to continuously repeat the configured sweep. Use
the EXIT key to stop the sweep. Data is not stored in the buffer.
•
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 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 example, 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 configured sweep points are 1V, 2V, 3V, 4V, and 5V, the sweep
will be 1V, 2V, 2.1V, 2.1V, and 2.1V.
