Function Details
SMU Compliance
SMU output values If you specify power compliance, the SMU changes the current or voltage
compliance every sweep step. Hence, the SMU can apply voltage or current with the
maximum power. Figure 7-26 shows the differences between the output with power
compliance and the output without power compliance, for MPSMU.
Figure 7-26 Allowable Current in Vol
tage Sweep (
0 V to 100 V, MPSMU)
NOTE If you specify power compliance, the measurement time increases slightly because
the B1500 adjusts the compliance for every sweep step.
To Set Compliance
The following points must be noted when setting the compliance.
• If the current compliance value is too low, the SMU will take a long settling
time.
• The SM
U will reach voltage compliance if the SMU cannot force the specified
current for th
e following reasons:
• Over current for test device.
• Another channel has reached compliance.
• Current measurement data of another channel has reached the limit f
or the
present measurement range.
