• First solution to apply both electrical delay
and insertion loss to enhance port extensions
• First approach to give reasonable alternative to building
in-fixture calibration standards or de-embedding fixture

Automatic Port Extensions – Step 1
• First, perform coaxial calibration at fixture connectors to remove errors
due to VNA and test cables
• At this point, only the fixture loss, delay and fixture mismatch remain
as sources of error.
