Rapid Characterization of High Speed Digital Channels using a Multiport VNA

Application Note Overview

Vector Network Analyzers (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 Device Under Tests (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.

In this application note from Rohde & Schwarz, discover the thermal advantages of testing an 8- port DUT with the R&S ZNBT VNA. Also, learn about the use of the ZNBT to assess and debug two differential pairs in a 20-inch backplane.
