Sweep branching

When using a Source Memory Sweep while performing limit tests, the normal sequence of
sweep memory points can be changed. This is useful when, based on the results of an ini-
tial test, a different set of tests are needed.
The sweep can branch to a specified memory location point, or proceed to the next mem-
ory location in the list. When a memory location is specified, the sweep will branch to that
memory location if the test is successful (PASS condition). If not successful (FAIL condi-
tion), the sweep proceeds to the next memory location in the list. With NEXT selected (the
default), the sweep proceeds to the next memory location in the list regardless of the out-
come of the test (PASS or FAIL condition).
Figure 10-5 shows a six-point sweep branching example. In this case, the unit is pro-
grammed to branch to location 7 when a pass conditions occurs at location 3.
