Logarithmic sweep with a current source
The following examples perform a logarithmic sweep using a current source. They perform the
following actions:
• Reset the instrument to its defaults.
• Set the source function to current.
• Set the source range to 100 mA.
• Set up a logarithmic sweep from 100 µA to 100 mA in 10 steps with a source delay of 10 ms, a
sweep count of 1, and a fixed source range. In TSP only, name the configuration list that is
created for this sweep CurrLogSweep.
• Set the measure function to current.
• Set the current range to 100 µA.
• Start the sweep.
No buffer is defined, so the data is stored in defbuffer1. See Reading buffers (on page 3-10
) for
more information on reading buffers.
