2. Guaranteed by design or characterization.
3. Test performed with C
4. This should not be confused with Clock Jitter, since the HMP8116 does not generate the sample clock. Thus, clock jitter is solely depen-
dent on the source of the CLK2 signal. The Vertical Sample Alignment parameter specifies how accurately samples align vertically from
one scan line to the next.
