* Testing was performed to determine if fretting occurs due to mechanical motion and to evaluate the integrity of the
Hypertac contact system relative to severe shock. To validate the test, low nanosecond event detection was performed
at 10 nanoseconds.
There were no events recorded.
** Testing was performed using a 6U Flight Chassis to determine if fretting occurs due to mechanical motion and to evalu-
ate the integrity of the test samples relative to severe mechanical environment. To validate the test, low nanosecond
event detection was performed at 50 nanoseconds.
There were no events recorded.

2. Propagation Delay and Skew
Propagation delay through the intrinsic connector assembly is estimated by making a measurement on the reflected signal
received on the same broadband fixture that is used to obtain the full vector scattering parameters. In these measurements,
there is no inclusion of any other pin lengths other than what is within the intrinsic connector.
