Setting up a sweep using SCPI commands
To set up a sweep using SCPI commands, you send one of the following commands:
•
:SOURce[1]:SWEep:<function>:LINear: Sets up a linear sweep for a fixed number of
measurement points.
•
:SOURce[1]:SWEep:<function>:LINear:STEP: Sets up a linear source sweep
configuration list and trigger model with a fixed number of steps.
•
:SOURce[1]:SWEep:<function>:LIST: Sets up a sweep based on a configuration list, which
allows you to customize the sweep.
•
:SOURce[1]:SWEep:<function>:LOG: Sets up a logarithmic sweep for a set number of
measurement points.
To create a sweep:
1. Set the source function using :SOURce[1]:FUNCtion[:MODE].
2. Set the source range using :SOURce[1]:<function>:RANGe.
3. Set any other source settings that apply to your sweep. You must set source settings before the
sweep function is called.
4. If you are using :SOURce[1]:SWEep:<function>:LIST, set up the source configuration list
for your sweep.

Model 2461 Interactive SourceMeter® Instrument Reference Manual
Description
How many times the sweep should repeat. You can select one of the following
options:
Finite: Set a specific number of times to repeat.
•
Infinite: The sweep will repeat until is it aborted.
•
Sets the source limit for measurements. The instrument cannot source levels that
exceed this limit.
Determines if the sweep is stopped immediately if a limit is exceeded. You can
select one of the following options:
ON: Abort the sweep if a limit is exceeded.
•
OFF: Complete the sweep even if a limit is exceeded.
•
The source range that is used for the sweep. You can select one of the following
options:
Best Fixed: The instrument selects a single fixed source range that will
•
accommodate all the source levels in the sweep. This avoids overshoots
during sweeps.
Auto: The instrument selects the most sensitive source range for each
•
source level in the sweep.
Fixed: The source remains on the range that is set when the sweep is
•
started. If a sweep point exceeds the source range capability, the source
will output the maximum level for that range.
