Summary:The present invention provides a system ( 100 ) that overcomes performance incongruities between a high-speed device ( 102 ) and commercial ATE ( 106 ). The system of the present invention provides an analog-to-analog sampler ( 104 ), having a clock input ( 118 ). The analog-to-analog sampler receives a first analog test signal ( 108 ) from the high-speed device, and converts it into a second analog test signal ( 116 ) at a desired rate, utilizing an analog-to-digital-to-analog conversion function ( 112 ) and a decimation function ( 114 ). The ATE system houses an analog capture component ( 120 ). The analog capture component has a clock input ( 122 ), and receives the second analog test signal for conversion into digital format. A series of clock signals ( 126 ) are generated from a common frequency reference source ( 124 ), to provide the necessary clock signals throughout the system.
