Step 3. Selects devices valid for the HCI test
This step judges whether each device is valid according to the current leak test
result. The IGLEAK.MES and IDLEAK.MES files are used to set up the 4155/4156
for this step.
As shown below, 24 devices are connected to the E5250A, and measured
individually by switching. For devices that fail this step, no further testing is
performed, and "0.0" is recorded.
Step 4. Characterizes the initial parameters
This step initially (before stress) measures parameters for the devices that were
determined to be valid by the previous step.
The PARAM.MES file sets up the 4155/4156.
A summary of the measurement setup saved in PARAM.MES is shown below. For
details of the setup data, GET the PARAM.MES file using the 4155/4156, and refer
to the setup displayed on the 4155/4156.
