Abstract :
We have achieved a test technology for mixed signal ATE suitable for use in a production test environment for the characterization of the loop response and VCO sensitivity of PLL´s having response times of a few microseconds. This is a task that was previously not possible on mixed-signal ATE as it requires a Time Measurement Unit (TMU) utilizing a digital interpolator capable of making high speed “consecutive, instantaneous frequency measurements”
