Staircase sweep commands
Table 10-3 summarizes remote commands used for linear and log staircase
sweep operation. See Section 18, “Configure voltage and current sweeps,” for
more details on these commands.
Staircase sweep programming example
As an example of linear staircase sweep operation, assume the SourceMeter is to
be used to generate the I-V characteristics of a diode. Many diode tests, such as
breakdown voltage and leakage current, require only single-point measurements.
Some, such as quality-assurance analysis of marginal parts, involve performing a
complete I-V sweep for detailed analysis.

Select current source sweep mode.
Specify sweep start current (n = current).
Specify sweep stop current (n = current).
Specify sweep step current (n = current).
Specify sweep center current (n = current).
Specify sweep span current (n = current).
Select voltage source sweep mode.
Specify sweep start voltage (n = voltage).
Specify sweep stop voltage (n = voltage).
Specify sweep step voltage (n = voltage).
Specify sweep center voltage (n = voltage).
