Abstract
A mixed signal integrated circuit testing system includes a system controller connected to a test head for controlling the testing operations of the mixed signal integrated circuit testing system. The test head is adapted to support a wide combination of both the analog and digital circuit testing modules. A DUT board, typically configured for a specific IC or family of ICs, is used to connect the circuit testing modules to the IC. The DUT board is connected to a DUT board interface that includes an analog DUT board interface adapter and a digital DUT board interface adapter. The digital DUT board interface adapter is connected directly to the digital circuit testing modules. The analog DUT board interface adapter is connected to a system configuration module that provides analog loading and conditioning circuitry as well as other circuitry that can be customized for testing specific ICs.
