Test Sequence — staircase sweep
The following program performs a staircase sweep. Using the source voltage measure cur-
rent (FVMI) method, this test will measure the current through a DUT (see Figure 2-8) at
eleven voltage steps (0V through 10V). The eleven readings are stored in the buffer and
displayed on the computer CRT at the conclusion of the test.
