Creating a User Level
Branching
Each of the four sequence levels has one primary branch and one secondary
branch. If the primary branch is taken, the destination is directed by the
"Find" statement. If the secondary branch is taken, the destination is
directed by the "else on" statement. The primary branch must be used
whereas the secondary branch can be turned off.
If both branch statements are simultaneously met, the primary branch will be
taken. Both branches can be directed to any active sequence level or to the
Trigger. When the trigger is seen, sequencing is over and the poststore
counter begins counting down to zero, at which time data storage is over.

"Acquisition Control" section for more information on configuring memory to
store posttrigger data.
Example
The following statement instructs the analyzer to start the Timer as the
sequence level is entered. It then will have 8 ns to find the bit pattern you
assigned to "patt1." If it finds "patt1," then the analyzer triggers. If it doesn't
find "patt1" in 8 ns, the sequence evaluation branches to sequence level 2.
Upon exiting previous sequence level:
Find patt1
else on Timer expired
4–24
Timer was restarted with a value of 8 ns
1 time then goto Trigger
1 time goto 2
