Accurate time measurement system circuit and method |
摘要 |
Disclosed is a method of measuring the time signal of an electronic device including steps for measuring a true signal and an inverted signal. The measured true path signal and inverted path signal are combined to reduce measurement error and provide an accurate measurement of the time signal of the device under test. Also disclosed is an interface for use between a device-under-test and test equipment. The interface includes means for alternately switching a time signal from the device-under-test to provide a true signal path and an inverted signal path for measurement. A system embodiment of the invention is also disclosed in which an interface and measuring means are used to alternately measure and combine a true signal and an inverted signal to provide an accurate time measurement result.
