This article demonstrates accurate differential S-parameter measurements obtained from a single-ended 2-port VNA using ultra-broadband baluns and attenuators. This measurement system is a cost-effective alternative to purchasing a multi-port test set for a VNA. 

The software-based solution enables accurate, repeatable evaluation of communication quality across networks, including cloud and virtual environments. 

In this article, Steve Sandler presents three viable solutions for measuring ultra-low impedance with a maximum of 10 ms, each of which can be performed using sophisticated and novel FFT based 3-port measurement. These methods involve applying digitally modulated patterns to create modulated load currents up to 1500 A and recording the resulting power rail voltage perturbations. 

Interconnect pioneers use premier electronics industry event to showcase wider digital cable solution capabilities.

Awarded the Best Paper Award at DesignCon 2024, this paper demonstrates that, for correlated data with PDN impedances in the sub-mΩ level, the impedance extracted from same-location top-bottom measurement can be significantly different from same-side adjacent via pair measurement, even if the physical separation is in the order of a mm

In this blog, Steve Sandler and Benjamin Dannan demonstrate how to determine how much CMRR is needed when introducing a ground loop isolator to correct the error in a 2-port measurement. 

Rohde & Schwarz efficiently tackles compliance verification challenges for PCIe 5.0 and 6.0 cables and connectors by automating the process with a new R&S ZNrun vector network analyzer automation suite option. 

A VNA equipped with time domain analysis that includes basic and advanced window and gating functionality can help produce more accurate and repeatable impedance measurements. Read on. 

In this tongue-in-cheek experiment that leads to actionable conclusions, Ben Dannan and Steve Sandler set out to discover a method to mitigate the lack of an isolation calibration step on a VNA.

Measuring low impedance components with a 2-port vector network analyzer (VNA) is an essential technique that typically requires a VNA that costs more than $20,000. In this article, see how the authors measured an MLCC using $500 and an open-source simulation tool.
