put will go high indicating the start of the first time
bin. The insertion delay from TRIGGER to SYNC/
BUSY is 45 ns. SYNC/BUSY will have 2.5 ns of in-
determinacy with respect to the trigger. As a re-
sult, the entire record starts with 2.5 ns of uncer-
tainty with respect to the trigger. This is not a
problem if the bin width is much longer than 2.5 ns
but may be a problem for shorter bin widths. In
these cases, the SYNC/BUSY output should be
used to trigger the experiment. Since the record is
synchronized to SYNC/BUSY, there will be no in-
determinacy of the time bins with respect to the
experiment. One way to accomplish this is to trig-
ger the SR430 with the experiment's master rate
generator and use the SYNC/BUSY (which is de-
layed from trigger by only 45 ns) to trigger the ac-
tual experiment.
