摘要： According to one embodiment of the invention, a method of sampling a signal is provided. The method includes receiving over a signal path an analog signal generated using a first clock signal by a first device. The method also includes sampling the analog signal using a second clock signal to generate a numeric representation of at least a portion of the analog signal. The frequencies of the first and the second clock signals differ from one another by a known amount. The method also includes communicating over the signal path the numeric representation for receipt by a second device. The signal path experiences loading and at least a majority of the loading of the signal path occurs between the sampler and the second device.

摘要： 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.

摘要： System and method for testing differential signal crossover in high-speed electronic equipment. A preferred embodiment comprises a test circuit coupled to a device under test (DUT) and an automatic test equipment (ATE). The test circuit comprises a pair of window comparators coupled to a differential mode signal from the DUT, each window comparator configured to compare one of two signals making up the differential mode signal with a voltage boundary when enabled by an enable signal. The ATE is configured to provide clock signals to the test circuit and the DUT and to process data produced by the test circuit to determine if the differential signal crossover meets timing constraints. The test circuit uses undersampling to enable testing of high frequency signals without requiring an extremely high sampling rate.
