Maximum compliance limits

Compliance principles

Compliance acts as a clamp. If the output reaches the compliance value, the

SourceMeter will attempt to prevent the output from exceeding that value. This

action implies that the source will switch from a V-source to an I-source (or from

an I-source to a V-source) when in compliance.

As an example, assume the following:

SourceMeter: V

DUT resistance: 10Ω

With a source voltage of 10V and a DUT resistance of 10Ω, the current through

the DUT should be: 10V/10Ω = 1A. However, because the compliance is set to

10mA, the current will not exceed that value, and the voltage across the

resistance is limited to 100mV. In effect, the 10V voltage source is transformed

into a 10mA current source with a 100mV compliance value.
