Compliance
Figure 3-10 Power Compliance Output Area
If you specify power compliance, SMUs can be swept at their maximum output
limits because the 4155B/4156B changes the V (or I) output range and I (or V)
compliance range during a V (or I) sweep. Figure 3-11 shows an example of the
difference in SMU output when power compliance is set and when power
compliance is not set.
Figure 3-11 Allowable I Output when the MPSMU Sweeps Voltage (0 V to 100 V)
If you specify power compliance, the measurement time increases slightly because
of the range changing for every step. When the ranges are changed during a sweep
to accommodate power compliance, the SMU output is momentarily set to 0 V.
