Abstract:
1. A test system for measurement of an insertion loss of a device under test having a filtered feed-through assembly including a conductive line, a ferrule and an oxide layer over the ferrule, comprising: a test fixture having a probe pin configured to contact the conductive line and a probe pin configured to pierce the oxide layer of the filtered feed-through assembly to establish a ground connection to the ferrule; an equivalent series resistance (ESR) measurement device coupled to the conductor probe pin of the test fixture and coupled to the ground connection pin of the test fixture, the ESR device operating to obtain insertion loss data; and a control module coupled to the equivalent series resistance measurement device, wherein the control module inputs a control signal to the equivalent series resistance measurement device and wherein the equivalent series resistance device transmits the obtained insertion loss data to the control module.
