(a) is the minimum time to wait after the
counter has been enabled to clock it.
(b) is the minimum time before the counter
has been disabled that it may be clocked.
(c) is the minimum time before the counter
is enabled that a clock pulse may be
applied with no effect on the state of the
counter.
(d) is the minimum time to wait after the
counter is disabled that a clock pulse may
be applied with no effect in the state of the
counter.
(b) and (c) may be negative numbers.

50-ohm termination to ground lo-
cated in each scope channel input.
All input and output cables to the
scope are equal lengths of 50-ohm
coaxial cable. Wire length should be
< 1/4 inch from TPin to input pin and
TPout to output pin.
Unused outputs are connected to a
50-ohm resistor to ground.
NOTE:
tsetup is the minimum time before the positive
transition of the clock pulse (C) that information must
be present at the input D or S.
thold is the minimum time after the positive
transition of the clock pulse (C) that information must
remain unchanged at the input D or S.
