Abstract
A system and method for testing multiple smart card devices in parallel and asynchronously are provided. The system includes a smart card module that may be easily inserted in a digital test system. The smart card module includes multiple smart card instrument channels, each one of which testing a separate smart card device independently and asynchronously from the others. The smart card instrument channels employ a novel modulation technique based on palette waveforms that are formed of transitions between two data bits.
