Skew [1] Typical < 1.5 ns; worst case = 2 ns
Recommended lead set Agilent 10498A
[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.
