About Stress/Measure Mode
In the Stress/Measure Mode, the subsite test is repeated a specified number of times. For each
individual test in the subsite, data is acquired for each subsite cycle. For example, if the subsite is
cycled five times, there are five sets of data and graphs for each test. You can execute up to 128
cycles.
The test sequence includes components for stressing, percent change, and target evaluation. The
following figure shows an example of a basic testing sequence. The components for stressing,
percent change, and target evaluation are shown in blue.
When subsite cycling is started, the first pass through the subsite is a pre-stress cycle. Tests are run
with no stressing. At the start of the next cycle, the configured stress (voltage or current) is applied to
all devices. After the stress period expires, the stress is removed and enabled tests are run. Each
additional stress cycle operates in the same manner. That is, the stress is applied for the specified
stress time, then all the enabled tests are run. Notice that after each test is run, the percent absolute
(Abs) change and targets are evaluated.
