Application Note Overview

Testing high-speed cables for data centers or consumer electronics is complex and time-consuming, requiring precise multiport measurements across high frequencies.

Engineers must verify each transmission lane and assess crosstalk—both near end (NEXT) and far end (FEXT). Traditional 4-port VNA setups demand multiple reconnections, taking up to a full day to test one 8-lane cable. This application note introduces an automated way that performs all compliance measurements automatically; processes results per standards like COM and ERL, and generates detailed pass/fail reports, which saves time, reduces errors, and ensures accurate, repeatable testing of high-speed cables.
