Test system including a test circuit board including resistive devices

摘要

A test system includes a device under test and a test circuit board. The device under test includes a plurality of contacts configured to provide output signals. The test circuit board may convey the output signals from the device under test to an analyzer. The test circuit board may include a dielectric layer, a via extending through the dielectric layer, a conductor formed on the dielectric layer and a resistive annular ring having a predetermined resistance value. The resistive annular ring may be formed around the via and may be electrically coupled between the via and the conductor.
