Sweep types
Sweeps allow you to program the instrument to step through specific voltage and
current values and perform measurements at each source value. The four basic
sweep types, which are described in the following paragraphs, include:
• Linear staircase
• Logarithmic staircase
•Custom
• Source memory
NOTE Only voltage or current sweeps can be performed. Sweep readings are
automatically stored in the buffer. See
Section 9 for details on the data
store (buffer).
Linear staircase sweep
As shown in Figure 10-1, this sweep steps from a start source value to an ending
(stop) source value. Programmable parameters include the start, stop, and step
source levels.
When this sweep is triggered to start, the output will go from the bias level to the
start source level. The output will then change in equal steps until the stop source
level is reached. With trigger delay set to zero, the time duration at each step is
determined by the source delay and the time it takes to perform the measurement
(NPLC setting). Note that the delay cannot change once a sweep is configured
and running and is the same for all steps.
