Performing limit tests
Perform the following steps to run limit tests:
Step 1. Configure test system.
As previously explained in Section 2, your test system could be as simple as connecting one or
two DUTs to the Model 6482. Adding a scanner to the test system allows you to test multiple
devices.
Step 2. Configure bias source and measure functions.
Configure the Model 6482 operation as follows:
1. Select the source channel by pressing the
SRC1
or
SRC2
key.
2. Set the source level value.
3. Press the
MSR1
or
MSR2
key to select the measurement channel, then choose the measure-
ment range.
Refer to

for more information.
Step 3. Configure limit tests.
Select and configure the following limit tests parameters as explained in
:
•
Set the H/W-LIMITS and S/W-LIMITS parameters.
