AC Overshoot Test Method of Implementation

The Overshoot test can be divided into two sub-tests: Overshoot amplitude and Overshoot area. The
purpose of this test is to verify that the overshoot value of the test signal is lower than or equal to the
conformance limit of the maximum peak amplitude allowed for overshoot as specified in the JEDEC
Standard JESD79E.
When there is an overshoot, the area is calculated based on the overshoot width. The Overshoot area
should be lower than or equal to the conformance limit of the maximum Overshoot area allowed as
specified in the JEDEC Standard JESD79E.
