Rapid Characterisation of High Speed Digital Channels using a Multiport VNA

Published by Rohde & Schwarz Inc.

Vector Network Analysers (VNA) are gaining popularity in the Signal Integrity community as Time Domain Measurement and Analysis tools. 

VNAs with 8 ports or more can provide significant decreases in test time by migrating from a 4-port measurement system to an 8-port measurement system. For tight tolerance DUTs that are barely within the test limit lines, small increases in accuracy can be realized by testing all of the test parameters at once, because the entire test setup is at the same temperature. This thermal advantage of testing an 8- port DUT is discussed.
