1. Typical skew measurements made at pod connector with
approximately 10 pF/50 KΩ load to GND; worst case skew
numbers are a calculation of worst case conditions through
circuits. Both numbers apply to any channel within the
pattern generator.
2. Channel 7 on the 3-state pods has been brought out in parallel
as a non 3-state signal. By looping this output back into the
3-state enable line, the channel can be used as a 3-state
enable.
