Abstract
In a tester for testing circuits, apparatus and methods for acquiring waveform data from a circuit under test. While a test program is being run by the tester, waveform acquisition strobe events are generated for application to a terminal of a circuit under test. A measurement circuit receives the waveform acquisition strobe events and applies each strobe event to the terminal of the circuit and generates result signals representing the result of applying the strobe events to the terminal. A capture memory receives and stores result signals generated by the measurement circuit.
