A New Calibration Method for Characterization of PCB Insertion Loss

Straight from Dgcon 2015 - The Main Signal & Power Integrity Event In Israel! http://www.dgcon.info/ Initiated by Dgtronix, Dgcon is the first Israeli conference targeted to provide the necessary technical knowledge, covering many aspects of Hardware Design. **This video is a property of Dgtronix and is for personal use only.

The Lecture: There are several existing techniques like Direct Loss Subtraction, Through-Reflection-Line (TRL) calibration and Automatic Fixture Removal (AFR) with 2XThrough fixtures for characterizing PCB unit length insertion loss. In this paper, a new method for characterizing PCB loss by using AFR with 1X Open fixtures is proposed. This new method has been proved to have the similar accuracy with TRL and AFR with 2X throughs, but can save much more PCB area and measurement time. Based on measurements of transmission lines with different reference impedance, the measurement bandwidth, accuracy, efficiency and cost of these techniques are compared. The Expert: Mike Resso is the Signal Integrity Application Scientist in the Component Test Division of Keysight Technologies and has over twenty-five years of experience in the test and measurement industry. His background includes the design and development of electro-optic test instrumentation for aerospace and commercial applications. His most recent activity has focused on the complete multiport characterization of high speed digital interconnects using Time Domain Reflectometry and Vector Network Analysis. He has authored over 30 professional publications including a book on signal integrity. Mike has been awarded one US patent and has twice received the Agilent “Spark of Insight” Award for his contribution to the company. He received a Bachelor of Science degree in Electrical and Computer Engineering from University of California.
