Abstract
A method for controlling a measurement system includes providing a variable bandwidth DC bias loop for biasing a DUT; providing an AC measurement loop for measuring AC parameters of the DUT; disabling the AC measurement loop and selecting a high bandwidth for the DC bias loop when rapid changes to the DC bias are to be made; and selecting a low bandwidth for said DC bias loop and enabling the AC measurement loop when AC measurements of the DUT are to be made.
