4. Enter the maximum power for the test device. An example of a transistor test with LLEC disabled
with a power threshold of 3 W and a voltage threshold of 12 V is shown in the "Vd-Id family of
curves with LLEC disabled" figure. Note that each threshold allows the test to be bounded. Also
note that the thresholds do not stop the test at exactly the threshold value, but only after the
threshold has been exceeded. One test point always exceeds the threshold. You can reduce the
amount that the threshold is exceeded by using smaller sweep step sizes.
