SYSTEM AND METHOD FOR EVALUATING HIGH FREQUENCY TIME DOMAIN IN EMBEDDED DEVICE PROBING |
摘要 |
A system and associated method for evaluating a high-frequency signal at a point of interest on a signal path from a remote signal at a remote pickup point on the signal path. The point of interest is located on a device under test that is coupled to test equipment via the signal path. The high-frequency signal at the point of interest is calculated from the remote signal at the remote pickup point with an inverse transfer function that eliminates degradation effects on the high-frequency signal that is transferred through the signal path. The inverse transfer function may be calculated from measurements acquired in a test signal transfer through a reference path that simulates electrical properties of the signal path, or configured to a predetermined function if electrical properties of the signal path are known.
