Performing limit tests
Step 1. Configure test system
As previously explained, testing the system could be as simple as connecting a DUT to the
Model 6487.
Step 2. Configure measurement
Configure the Model 6487 for the desired measurement as covered in the previous sections
of this manual.
Step 3. Configure limit tests
Configure the Model 6487 for the limit tests as explained in
.
Step 4. Start testing process
To enable the limit tests, press the LIMIT key—the testing process will start when LIMIT
