Function Details
SMU Compliance
SMU Compliance
Compliance is the output limiter to prevent damage to the test device from
overcurrent, overvoltage, or overpower. Voltage compliance is for the current output
channels, and current compliance is for the voltage output channels.
When a channel reaches compliance, the channel acts as a constant voltage source or
a constant current so
urce. The channel keeps the output value when reaching
compliance.
Compliance can be set with the same resolution and accuracy as output current or
output v
oltage. For the values, refer to “Specifications” on page 2-33.
Polarity and Output Area
• Polarity of current compliance
Agilent B1500 automatically sets current compliance for both positive and
negative p
olarity. For opposite polarity as the output voltage, the compliance
value is increased by an amount that is 2.5 % to 12 % of the range value in the
lowest range that covers the specified compliance value. See Figure 7-24.
• Polarity of voltage compliance
Agilent B1500 automatically sets voltage compliance to the same polarity as the
output curren
t. There is no compliance for opposite polarity.
